Some systems analysts maintain that source documents are unnecessary. They say that an input can be entered directly into the system, without wasting time in an intermediate step.
Do you agree? Can you think of any situations where source documents are essential?

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:

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

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.

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.

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.

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.

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

Following are the program to the given question:

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:

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 .

Here is the function replace_all:

def replace_all(target_string,find_string,replace_string):

   result_string = replace_string.join(target_string.split(find_string))  

   return result_string

#if you want to see the working of this function then you can call this function using the following statements:

target_string = "In case I don't see ya, good afternoon, good evening, and good night!"

find_string = "good"

replace_string = "bad"

print(replace_all(target_string, find_string, replace_string)

Explanation:

The above program has a function called replace_all that accepts three arguments i.e target_string, a string in which to search ,find_string, a string to search for and replace_string, a string to use to replace every instance of the value of find_string. The function has the following statement:

replace_string.join(target_string.split(find_string))  

split() method in the above statement is splits or breaks the target_string in to a list of strings based on find_string. Here find_string is passed to split() method as a parameter which works as a separator. For example above:

target_string = In case I don't see ya, good afternoon, good evening, and good night!

find_string = good

After using target_string.split(find_string) we get:

["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night']

Next join() method is used to return a string concatenated with the elements of target_string.split(find_string). Here join takes the list ["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night'] as parameter and joins elements of this list by 'bad'.

replace_string = bad

After using replace_string.join(target_string.split(find_string))  we get:

In case I don't see ya, bad afternoon, bad evening, and bad night!

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:

True

Explanation:

A guest Operating System (OS) is a secondary OS to the main installed OS which is the host Operating System (OS). Guest OS can either be a part of a partition or a Virtual Machine (VM). This guest OS is used as a substitute to the host OS.

vSphere Web Client can be installed by using a CD-ROM, DVD or ISO image which has the installation image to make a Virtual Machine (VM) functional.

Answer:

Explanation:

In such a situation like this one, the first step would be to identify the brand and model of the video card itself. Once you find the brand and model you can simply go over to the brand manufacturer's website and go to the driver downloads section. There you simply search for the model series of the video card in your computer and download/install the latest version. The brand manufacturer's official website always has the most up to date drivers for all of their hardware.

Answer:

sentence = "hello wow a stores good"

same_letter_count = 0

sentence_list = sentence.split()

for s in sentence_list:

   if s[0] == s[-1]:

       same_letter_count += 1

print(same_letter_count)

Explanation:

*The code is in Python.

Initialize the sentence with a string

Initialize the same_letter_count as 0

Split the sentence using split method and set it to the sentence_list

Create a for loop that iterates through the sentence_list. If the first and last of the letters of a string are same, increment the same_letter_count by 1

When the loop is done, print the same_letter_count

Answer:

Option D, all of the above, is the right answer.

Explanation:

A Boolean expression is an expression in Computer Science. It is employed in programming languages that create a Boolean value when it is evaluated. There may be a true or false Boolean value. These expressions correspond to propositional formularies in logic. In Boolean expression, the  expression 3 > 5 is evaluated as false while  5 > 3 is evaluated as true

Boolean expressions control  all of the above method execution and as such option d is correct.

A Boolean expression is known to be a kind of logical statement that is said to be one of the two options that is it can be TRUE or FALSE .

Conclusively, Note that Boolean expressions are used to compare two or more data of any type only if  both parts of the expression have equal basic data type.  Boolean expressions control recursion, conditional execution and alternative execution.

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
