Answer:

while True:

   number1 = input("Enter the number1: ")

   number2 = input("Enter the number2: ")

   if number1.isnumeric() and number2.isnumeric():

       break

number1 = int(number1)

number2 = int(number2)

print("The sum is: " + str(number1 + number2))

Explanation:

*The code is in Python.

Create an infinite while loop. Inside the loop, Get the number1 and number2 from the user. Check if they are both numeric values. If they are, stop the loop (Otherwise, the program keeps asking for the numbers).

When the loop is done, convert the numbers to integer numbers

Calculate and print their sum

1. Blockchain Technology: Blockchain is a distributed ledger technology that lets data to be stored globally on its servers and it is based on a P2P topology which makes it difficult for someone to tamper with the network.

It can be used as a cryptocurrency wallet that supports BitCoin, Ethereum, etc.

An advantage of it is that it is distributed among several users and stable.

A disadvantage for a developing country like Ghana is that once a blockchain is sent, it cannot go back which brings up the question of security.

2.Artificial Intelligence: This technology is simply the simulation of human intelligence in machines. AI can be used for problem-solving and learning. An advantage of AI is that it reduces human error and is fast in solving problems. A disadvantage of AI is that its expensive to maintain and also it does not improve with experience.

3. Global Positioning System: GPS is a satellite-based positioning system that is used to pinpoint and track location. It has the advantage of being available worldwide and information is provided to users in real-time. One disadvantage of the GPS for a developing country like Ghana is that electromagnetic interference can affect the accuracy of the GPS.

4. 5G Network: This is the 5th generation of mobile internet connectivity that gives super fast download and upload speeds when compared to its predecessors 4G, 3G, 2G, and Edge networks.

One major disadvantage of 5G for a developing country like Ghana is that it is expensive and quite unknown and its security and privacy issues are yet to be resolved.

5. Lasers: This isn't a new technology as it has been in use for some time already but its importance cannot possibly be over-emphasized. LASER is an acronym that means Light Amplification by the Stimulated Emission of Radiation.

It is precise and accurate in cutting when compared to thermal and other conventional cutting methods. It is being used in surgeries that require the highest levels of accuracy with great success.

A disadvantage of Laser technology is that it is expensive to use and maintain.

System.gc()

Explanation:

System.gc() can be defined as the method which can be used to effectively request for garbage collection because they runs the garbage collector, which in turn enables JMV which is fully known as JAVA VIRTUAL MACHINE to claim back the already unused memory space of the objects that was discarded for quick reuse of the memory space , although Java virtual machine often perform garbage collection automatically.

Answer:

Explanation:

The system will be deadlock free if the below two conditions holds :

Proof below:

Suppose N = Summation of all Need(i), A = Addition of all Allocation(i), M = Addition of all Max(i). Use contradiction to prove.

Suppose this system isn't deadlock free. If a deadlock state exists, then A = m due to the fact that there's only one kind of resource and resources can be requested and released only one at a time.

Condition B, N + A equals M < m + n. Equals N + m < m + n. And we get N < n. It means that at least one process i that Need(i) = 0.

Condition A, Pi can let out at least 1 resource. So there will be n-1 processes sharing m resources now, Condition a and b still hold. In respect to the argument, No process will wait forever or permanently, so there's no deadlock.

def max_magnitude(user_val1, user_val2):

     if abs(user_val1)>abs(user_val2):

           return user_val1

     else:

           return user_val2

val1 = int(input("Value 1: "))

val2 = int(input("Value 2: "))

print(max_magnitude(val1,val2))

Explanation:

This line imports the math module in the program

import math

This line declares the function with two parameters

def max_magnitude(user_val1, user_val2):

The if condition gets the absolute value of both integers and compares them; The integer with greater magnitude is returned, afterwards

     if abs(user_val1)>abs(user_val2):

           return user_val1

     else:

           return user_val2

The main method starts here

The next two lines prompt user for input

val1 = int(input("Value 1: "))

val2 = int(input("Value 2: "))

This line gets the integer with higher magnitude

Answer:

I am writing a C++ program using loops instead of nested if statements.

#include <iostream> // to use input output functions

using namespace std; // to identify  objects like cin cout

void cells(int cells[],int days){ /* function that takes takes one array of integers cells, one integer days representing the number of days to simulate. */

int pos ,num=0; //declares variables pos for position of two adjacent cells and num to iterate for each day

int result[9]; //the updated output array

while (num< days)   { //this loop keeps executing till the value of num is less than the value of number of days

num++;

for(pos=1;pos<9;pos++)   //this loop has a pos variable that works like an index and moves through the cell array

    result[pos]=(cells[pos-1])^ (cells[pos+1]); //updated cell state determined by the previous and next cells (adjacent cells) by bitwise XOR operations

     for(pos=1;pos<9;pos++) //iterates through the array

         cells[pos]=result[pos];    } //the updated cells state is assigned to the cell array simultaneously

   for(pos=1;pos<9;pos++) //iterates through the array and prints the resultant array that contains the updated active and inactive cells values

        cout << result[pos]; }

int main() { //start of the main function body

int j,day;

int output[9];

*/the two cells on the ends (first and last positions of array) have single adjacent cell, so the other adjacent cell can be assumed to be always inactive i.e. 0 */

output[0]=output[9]=0;

for(j=1;j<9;j++) //takes the input array from user

cin >> output[j];

cin >> day;

cells(output,day); } //calls the function cells to print the array with active and inactive cells states.

Explanation:

The program is well explained in the comments mentioned with every statement of the program. I will explain with the help of example:

Suppose the user enters the array = [1,0,0,0,0,1,0,0] and days=1

The while loop checks if the value of num is less than that of days. Here num is 0 and days is 1 So this means that the body of while loop will execute.

In the body of while loop the value of num is incremented by 1. The first loop initializes a variable pos for position of adjacent cells. The statement is a recursive statement result[pos]=(cells[pos-1])^ (cells[pos+1]) that uses previous state for updating the state of other cells. The “^” is the symbol used for bitwise exclusive operator. In bitwise XOR operations the two numbers are taken as operands and XOR is performed on every bit of two numbers. The result of XOR is 1 if the two bits are not same otherwise 0. For example XOR of 1^0 and 0^1 is 1 and the XOR of 0^0 and 1^1 is 0. The second for loop update the cell information of all cells simultaneously. The last loop prints the updated cells states.

The main function takes the input array element from user and the value for the days and calls the cells function to compute the print the active and inactive cells state information.

The screenshot of the program along with its output are attached.

Answer:

def find_max(num_1, num_2):

   max_val = 0.0

   if (num_1 > num_2): # if num1 is greater than num2,

       max_val = num_1 # then num1 is the maxVal.

   else: # Otherwise,

       max_val = num_2 # num2 is the maxVal

   return max_val

max_sum = 0.0

num_a = float(input())

num_b = float(input())

num_y = float(input())

num_z = float(input())

max_sum = find_max(num_a, num_b) + find_max(num_y, num_z)

print('max_sum is:', max_sum)

Explanation:

I added the missing part. Also, you forgot the put parentheses. I highlighted all.

To find the max_sum, you need to call the find_max twice and sum the result of these. In the first call, use the parameters num_a and num_b (This will give you greater among them). In the second call, use the parameters num_y and num_z (This will again give you greater among them)

Platform as a Service (PaaS).

Explanation:

In this scenario, an app developer is shopping for a cloud service that will allow him to build code, store information in a database and serve his application from a single place. The type of cloud service he is looking for is a platform as a service (PaaS).

In Computer science, Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.

The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.

Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).

Hence, the advantage of the Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.

These are the different types of Platform as a Service;

1. Private PaaS.

2. Public PaaS.

3. Hybrid PaaS.

4. Mobile PaaS.

5. Communications PaaS.

6. Open PaaS.

The software developers can choose any of the aforementioned types of PaaS that is suitable, effective and efficient for their applications development. Some examples of PaaS providers are Google, Microsoft, IBM, Oracle etc.

Answer:

(a) values[0].length

Explanation:

In programming languages such as Java, an array is a collection of data of the same type. For example, a and b below are an example of an array.

a = {5, 6, 7, 9}

b = {{2,3,4}, {3,5,4}, {6,8,5}, {1,4,6}}

But while a is a one-dimensional array, b is a regular two-dimensional array. A two-dimensional array is typically an array of one-dimensional arrays.

Now, a few thing to note about a two-dimensional array:

(i) The number of rows in a 2-dimensional array is given by;

arrayname.length

For example, to get the number of rows in array b above, we simply write;

b.length which will give 4

(ii) The number of columns in a 2-dimensional array is given by;

arrayname[0].length

This is with an assumption that all rows have same number of columns.

To get the number of columns in array b above, we simply write;

b[0].length which will give 3

Therefore, for a regular two-dimensional array named values, the number of columns is represented by: values[0].length

Answer:

B. Device boot order

Explanation:

The Device boot order makes a list of all the possible devices a system should check to in the operating system's boot files, as well as the proper sequence they should be in. Removable devices, hard drives, and flash drives are some devices that can be listed in the device boot order.

For the user whose computer displays a 'non-bootable drive' error, the device boot order would check all the devices listed to attempt booting from any of them. These devices might be in the order of removable discs, CD-ROM, hard drive. If all the options do not work, the computer would then do a Network boot. The order in which the devices are listed can be altered by the user.

Answer:

for (var i = 0; i <20; i++)

{

var lineY = 20 + (i * 20);

line(0, lineY, 400, lineY);

}

Explanation:

To turn the loop while to for loop, you start by considering the iterating variable i and its iterating operations which are;

var i = 0; while (i < 20) and i++;

Where var i = 0; is the initializing statement

(i < 20) is the conditional statement

i++ is the increment

The next is to combine these operations to a for loop; using the following syntax: for(initializing; condition; increment){}

This gives: for(var i = 0; i<20; i++)

Hence, the full code snippet is:

for (var i = 0; i <20; i++)

{

var lineY = 20 + (i * 20);

line(0, lineY, 400, lineY);

}

Explanation:

A program is portable if it is not platform dependent. In other words, if the program is not tightly coupled to a particular platform, then it is said to be portable. Portable programs can run on multiple platforms without having to do much work. By platform, we essentially mean the operating system and hardware configuration of the machine's CPU.

Examples of portable programs are those written in;

i. Java

ii. C++

iii. C

Answer:

c. a key found on Windows-oriented computer keyboards.

Answer:

a. 255.255.255.0 (class C)

b. 255.255.255.224

Explanation:

Here, we want to give the implied subnet mask of the given classful IPV4 address

We proceed as follows;

Given IPv4 address: 200.200.200.200

Classes

Class A : 0.0.0.0 to 127.255.255.255

Class B: 128.0.0.0 to 191.255.255.255

Class C: 192.0.0.0 to 223.255.255.255

Class D: 224.0.0.0 to 239.255.255.255

so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0

In CIDR(Classless Inter Domain Routing)

subnet /27 bits means 27 1s and 5 0s. so subnet

i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .

Answer:

I am writing a C program.

#include <stdio.h> // for using input output functions

#include <stdbool.h> // for using a bool value as data type

int main() { // start of the main() function body

 int count=0; //count the number of entries

 double gallons, miles, MilesperGallon, combined_avg, sum; //declare variables

 while(true) {// takes input gallons and miles value from user and computes avg miles per gallon

      printf( "Enter the gallons used (-1 to stop): \n" ); //prompts user to enter value of gallons or enter -1 to stop

      scanf( "%lf", &gallons );//reads the value of gallons from user

   if ( gallons == -1 ) {// if user enters -1

     combined_avg = sum / count; //displays the combined average by dividing total of miles per drives to no of entries

     printf( "Combined miles per gallon for all tankfuls:  %lf\n", combined_avg ); //displays overall average value  

     break;} //ends the loop

     printf( "Enter the miles driven: \n" ); //if user does not enter -1 then prompts the user to enter value of miles

     scanf( "%lf", &miles ); //read the value of miles from user

MilesperGallon = miles / gallons; //compute the miles per gallon

printf( "The miles per gallon for tankful:  %lf\n", MilesperGallon ); //display the computed value of miles per gallon

  sum += MilesperGallon; //adds all the computed miles per gallons values

   count += 1;  } } //counts number of tankfuls (input entries)

Explanation:

The program takes as input the miles driven and gallons used for each tankful. These values are stored in miles and gallons variables. The program calculates and displays the miles per gallon MilesperGallon obtained for each tankful by dividing the miles driven with the gallons used. The while loop continues to execute until the user enters -1. After user enters -1, the program calculates and prints the combined miles per gallon obtained for all tankful. At the computation of MilesperGallon for each tankful, the value of MilesperGallon are added and stored in sum variable. The count variable works as a counter which is incremented to 1 after each entry. For example if user enters values for miles and gallons and the program displays MilesperGallon then at the end of this iteration the value of count is incremented to 1. This value of incremented for each tankful and then these values are added. The program's output is attached.

Answer:

Chart styles

Explanation:

In PowerPoint, once you have inserted a chart (e.g a bar or pie chart), the format tab would be enabled so that you can format your chart to your taste. In this format tab, there are a bunch of tab groups such as:

(i) Chart styles: This allows you to typically change the component background colors of your chart.

(ii) Data: This contains sub-tabs that allow you to edit and select the data on your chart.

(iii) Type: This contains sub-tabs such as "Change Chart Type" which will allow you to change the type of the chart. For example if you were using a pie chart and you want to change it to a bar chart or any other chart, you can do that here.

(iv) Chart Layouts: This allows to change or modify how the selected chart is laid out.

Answer:

Here is the python method:

def is_power(n1, n2): # function that takes two positive integers n1 and n2 as arguments

   if(not n1>0 and not n2>0): #if n1 and n2 are not positive integers

       print("The number is not a positive integer so:") # print this message if n1 and n2 are negative

       return None # returns none when value of n1 and n2 is negative.

   elif n1 == n2: #first base case: if both the numbers are equal

       return True #returns True if n1=n2

   elif n2==1: #second base case: if the value of n2 is equal to 1

       return False #returns False if n2==1

   else: #recursive step

       return is_divisible(n1, n2) and is_power(n1/n2, n2) #call divisible method and is_power method recursively to determine if the number is the power of another

Explanation:

Here is the complete program.

def is_divisible(a, b):

   if a % b == 0:

       return True

   else:

       return False

def is_power(n1, n2):

   if(not n1>0 and not n2>0):

       print("The number is not a positive integer so:")  

       return None  

   elif n1 == n2:

       return True

   elif n2==1:

       return False

   else:

       return is_divisible(n1, n2) and is_power(n1/n2, n2)  

print("is_power(10, 2) returns: ", is_power(10, 2))

print("is_power(27, 3) returns: ", is_power(27, 3))

print("is_power(1, 1) returns: ", is_power(1, 1))

print("is_power(10, 1) returns: ", is_power(10, 1))

print("is_power(3, 3) returns: ", is_power(3, 3))

print("is_power(-10, -1) returns: ", is_power(-10, -1))  

The first method is is_divisible method that takes two numbers a and b as arguments. It checks whether a number a is completely divisible by number b. The % modulo operator is used to find the remainder of the division. If the remainder of the division is 0 it means that the number a is completely divisible by b otherwise it is not completely divisible. The method returns True if the result of a%b is 0 otherwise returns False.

The second method is is_power() that takes two numbers n1 and n2 as arguments. The if(not n1>0 and not n2>0) if statement checks if these numbers i.e. n1 and n2 are positive or not. If these numbers are not positive then the program prints the message: The number is not a positive integer so. After displaying this message the program returns None instead of True of False because of negative values of n1 and n2.

If the values of n1 and n2 are positive integers then the program checks its first base case: n1 == n2. Suppose the value of n1 = 1 and n2 =1 Then n1 is a  power of n2 if both of them are equal. So this returns True if both n1 and n2 are equal.

Now the program checks its second base case n2 == 1. Lets say n1 is 10 and n2 is 1 Then the function returns False because there is no positive integer that is the power of 1 except 1 itself.

Now the recursive case return is_divisible(n1, n2) and is_power(n1/n2, n2)  calls is_divisible() method and is_power method is called recursively in this statement. For example if n1 is 27 and n2 is 3 then this statement:

is_divisible(n1, n2) returns True because 27 is completely divisible by 3 i.e. 27 % 3 = 0

is_power(n1/n2,n2) is called. This method will be called recursively until the base condition is reached. You can see it has two arguments n1/n2 and n2. n1/n2 = 27/3 = 9 So this becomes is_power(9,3)

The base cases are checked. Now this else statement is again executed  return is_divisible(n1, n2) and is_power(n1/n2, n2) as none of the above base cases is evaluated to true. when is_divisible() returns True as 9 is completely divisible by 3 i.e. 9%3 =0 and is_power returns (9/3,3) which is (3,3). So this becomes is_power(3,3)

Now as value of n1 becomes 3 and value of n2 becomes 3. So the first base case elif n1 == n2: condition now evaluates to true as 3=3. So it returns True. Hence the result of this statement print("is_power(10, 2) returns: ", is_power(10, 2))  is:                                                                                                

is_power(27, 3) returns:  True

Answer:

def word_count(words):

   return len(words.split(" "))

print(word_count("This is Python."))

Explanation:

*The code is in Python.

Create a function called word_count that takes one parameter, words

Split the words using split function, use " " for the delimiter, and return the length of this using len function.

Note that split function will give you a list of strings that are written with a space in the words. The len function will just give you the length of this list.

Call the word_count function with a string parameter and print the result.
