Write a program that prompts the user to enter: The cost of renting one room The number of rooms booked The number of days the rooms are booked The sales tax (as a percent). The program outputs: The cost of renting one room The discount on each room as a percent The number of rooms booked The number of days the rooms are booked The total cost of the rooms The sales tax The total billing amount. Your program must use appropriate named constants to store special values such as various discounts.
Answer:
Written in Python
cost = float(input("Cost of one room: "))
numrooms = int(input("Number of rooms: "))
days = int(input("Number of days: "))
salestax = float(input("Sales tax (%): "))
print("Cost of one room: "+str(cost))
print("Discount: 0%")
print("Number of rooms: "+str(numrooms))
print("Number of days: "+str(days))
totalcost = numrooms * cost
print("Total cost: "+str(totalcost))
salestax = salestax * totalcost/100
print("Sales tax: "+str(salestax))
print("Total Billing: "+str(salestax + totalcost))
Explanation:
The next four lines prompts user for inputs as stated in the question
cost = float(input("Cost of one room: "))
numrooms = int(input("Number of rooms: "))
days = int(input("Number of days: "))
salestax = float(input("Sales tax (%): "))
The following line prints cost of a room
print("Cost of one room: "+str(cost))
The following line prints the discount on each room (No information about discount; So, we assume it is 0%)
print("Discount: 0%")
The following line prints number of rooms
print("Number of rooms: "+str(numrooms))
The following line prints number of days
print("Number of days: "+str(days))
The following line calculates total cost of rooms
totalcost = numrooms * cost
The following line prints total cost
print("Total cost: "+str(totalcost))
The following line calculates sales tax
salestax = salestax * totalcost/100
The following line prints sales tax
print("Sales tax: "+str(salestax))
The following line calculates and prints total billings
print("Total Billing: "+str(salestax + totalcost))

This program will calculate the rise in ocean levels over 5, 10, and 50 years, Part of the program has been written for you. The part that has been written will read in a rise in ocean levels (per year) in millimeters. This value is read into a variable of type double named risingLevel. You will be completing the program as follows Output the value in risingLevel. This should be the first line of output. The output should be as follows (assume risingLevel has a value of 2.1) Level: 2.1 The number of millimeters higher than the current level that the ocean's level will be in 5 years (assuming the ocean is rising at the rate of risingLevel per year). This is your second line of output. The output will be as follows Years: 5, Rise: 10.5 The number of millimeters higher than the current level that the ocean's level will be in 10 years (assuming the ocean is rising at the rate of risingLevel per year). This is your third line of output. The output will be as follows (for a risingLevel" of 2.1 Years: 10, Rise: 21 The number of millimeters higher than the current level that the ocean's level will be in 50 years (assuming the ocean is rising at the rate of risingLevel per year). This is your final line of output.The output will be as follows (for a risingLevel" of 2.1) Years: 50, Rise: 105 For each of the above you need to output the number of years and the total rise in ocean levels for those years. This is all based on the value in risingLevel For example: ArisingLevel of 2.1 for 5 years would have the following output: Level: 2.1 Years: 5, Rise: 10.5 Years: Years: 50, Rise: 105 10, Rise: 21 Your output must have the same syntax and spacing as above
Answer:
Here is the C++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
int main(){ //start of main method
double risingLevel; //declares a double type variable to hold rising level
cin>>risingLevel; //reads the value of risingLevel from user
cout<<"Level: "<<risingLevel<<endl; //displays the rising level
cout << "Years: 5, Rise: " << risingLevel * 5<<endl; //displays the rise in ocean level over 5 years
cout << "Years: 10, Rise: " << risingLevel * 10<<endl; //displays the rise in ocean level over 10 years
cout << "Years: 50, Rise: " << risingLevel * 50<<endl; //displays the rise in ocean level over 50 years
}
Explanation:
The program works as follows:
Lets say the user enters rising level 2.1 then,
risingLevel = 2.1
Now the first print (cout) statement :
cout<<"Level: "<<risingLevel<<endl; prints the value of risingLevel on output screen. So this statement displays:
Level: 2.1
Next, the program control moves to the statement:
cout << "Years: 5, Rise: " << risingLevel * 5<<endl;
which computes the rise in ocean levels over 5 years by formula:
risingLevel * 5 = 2.1 * 5 = 10.5
It then displays the computed value on output screen. So this statement displays:
Years: 5, Rise: 10.5 Next, the program control moves to the statement:
cout << "Years: 10, Rise: " << risingLevel * 10<<endl;
which computes the rise in ocean levels over 10 years by formula:
risingLevel * 10 = 2.1 * 10 = 21
It then displays the computed value on output screen. So this statement displays:
Years: 10, Rise: 21
Next, the program control moves to the statement:
cout << "Years: 50, Rise: " << risingLevel * 50<<endl;
which computes the rise in ocean levels over 50 years by formula:
risingLevel * 50 = 2.1 * 50 = 105
It then displays the computed value on output screen. So this statement displays:
Years: 50, Rise: 105 Hence the output of the entire program is:
Level: 2.1 Years: 5, Rise: 10.5 Years: 10, Rise: 21 Years: 50, Rise: 105
The screenshot of the program and its output is attached.
P5.30 Having a secure password is a very important practice, when much of our information is stored online. Write a program that validates a new password, following these rules: •The password must be at least 8 characters long. •The password must have at least one uppercase and one lowercase letter. •The password must have at least one digit. Write a program that asks for a password, then asks again to confirm it. If the passwords don’t match or the rules are not fulfilled, prompt again. Your program should include a function that checks whether a password is valid.
Answer:
def check_password(password):
is_short = False
has_uppercase = False
has_lowercase = False
has_digit = False
if len(password) < 8:
is_short = True
for p in password:
if p.isupper():
has_uppercase = True
if p.islower():
has_lowercase = True
if p.isdigit():
has_digit = True
if is_short == False and has_uppercase and has_uppercase and has_digit:
return True
else:
return False
while True:
password = input("Enter your password: ")
password2 = input("Enter your password again: ")
if password == password2 and check_password(password):
break
Explanation:
Create a function named check_password that takes one parameter, password
Inside the function:
Initialize the is_short, has_uppercase, has_lowercase, and has_digit as False. These variables will be used to check each situation
Check the length of the password using len() method. If it is smaller than 8, set is_short as True
Create a for loop that iterates through password. Check each character. If a character is uppercase, set the has_uppercase as True (use isupper() function). If a character is lowercase, set the has_lowercase as True (use islower() function). If a character is a digit, set the has_digit as True (use isdigit() function).
When the loop is done, check the value of is_short, has_uppercase, has_lowercase, and has_digit. If is_short is False and other values are True, return True. Otherwise, return False
Create an indefinite while loop, that asks the user to enter password twice. Check the entered passwords. If they are equal and the check_password function returns True, stop the loop. This implies that both passwords are same and password is valid.
Why is it important for element IDs to have meaningful names?
Answer:
Explanation:
In programming, it is very important that element ID's have meaningful names because it allows anyone reading the code to be able to easily identify what that element is and where it is most likely to be found in the code. This also applies to variables in every programming language. The clearer and more unique the name is the easier it becomes to know what that variable or element ID is representing which ultimately makes reading and debugging the code that much easier. This means that the entire process becomes more efficient as well.
It is vital for element IDs to have meaningful names due to the fact that it allows easy identification of the codes.
Element IDs refer to the id property of the interface of the element. It should be noted that the id property is unique in a document.
Element IDs should have meaningful names due to the fact that it allows east identification of the codes. This makes it easy for the person reading the code to identify them easily. The uniqueness of an element ID is vital to know what it represents.

This assignment involves writing a Python program to compute the average quiz grade for a group of five students. Your program should include a list of five names. Using a for loop, it should successively prompt the user for the quiz grade for each of the five students. Each prompt should include the name of the student whose quiz grade is to be input. It should compute and display the average of those five grades and the highest grade. You should decide on the names of the five students. Your program should include the pseudocode used for your design in the comments.
Answer:
Here is the Python program along with the comments of program design
#this program is designed to compute the average quiz grades for a group of five students
students = ["Alex", "John", "David", "Joseph", "Mathew"] #create a list of 5 students
grades = [] # create an empty list to store the grades in
for student in students: #loop through the students list
grade = input("Enter the quiz grade for "+student+": ") #prompt the user for the quiz grade of each student
#store the input grades of each student to grade
grades.append(int(grade)) # convert the grade to an integer number and append it to the list
print("Grades are:", grades) #display the grades of five students
average = sum(grades) / len(grades) #compute the average of five grades
print("The average of grades is:", average) #display the average of five grades
highest = max(grades) #compute the highest grade
print("The highest grade is:", highest) #print highest grade
Explanation:
The program first creates a list of 5 students who are:
Alex
John
David
Joseph
Mathew
It stores these into a list named students.
Next the program creates another list named grades to store the grades of each of the above students.
Next the program prompts the user for the quiz grade for each of the five students and accepts input grades using input() method. The statement contains student variable so each prompt includes the name of the student whose quiz grade is to be input. Each of the grades are stored in grade variable.
Next the append() method is used to add each of the input grades stored in grade to the list grades. The int() method is used to first convert these grades into integer.
Next print() method is used to display the list grades on output screen which contains grades of 5 students.
Next the average is computed by taking the sum of all input grades and dividing the sum by the total number of grades. The sum() method is used to compute the sum and len() method is used to return the number of grades i.e. 5. The result is stored in average. Then the print() method is used to display the resultant value of average.
At last the highest of the grades is computed by using max() method which returns the maximum value from the grades list and print() method is used to display the highest value.
The screenshot of the program and its output is attached.

Consider the following class declaration: public class Square { private double sideLength; public double getArea() { return sideLength * sideLength; } public double getSideLength() { return sideLength; } } Assuming that a no-arg constructor already exists, write an overloaded constructor for this class. It should accept an argument that is copied into the sideLength field. The parameter’s name is s.
Answer:
Here is the constructor:
public Square(double s) { //constructor name is same as class name
sideLength = s; } //s copied into sideLength field
Explanation:
The above constructor is a parameterized constructor which takes a double type variable s as argument. The name of constructor is same as the name of class.This constructor requires one parameters. This means that all declarations of Square objects must pass one argument to the Square() constructor as constructor Square() is called based on the number and types of the arguments passed and the argument passed should be one and of type double.
Here is where the constructor fits:
public class Square {
private double sideLength;
public Square(double s) {
sideLength = s; }
public double getArea() {
return sideLength * sideLength;}
public double getSideLength() {
return sideLength; } }

https://brainly.com/question/24395331
A user is asked to type a caption for a photo in a web form's text field. If the caption didn't end with a punctuation mark (. ! ?), a period should automatically be added. A common error is to end with a comma, which should be replaced by a period. Another common error is to end with two periods, which should be changed to one period (however, ending with three periods (or more) indicates elipses so should be kept as is). The corrected caption is output. If the input is "I like pie", the output is "I like pie." If the input is "I like pie!", the output remains "I like pie!" If the input is "Coming soon…", the output remains "Coming soon…"
Answer:
Here is the c++ program:
#include <iostream> //to use input output functions
using namespace std; //to identify objects cin cout
int main() { //start of main function
string caption; //stores the caption
int last_index; //stores the index position of the last character of caption
char last_character; //stores the last character of the caption
cout<<"Please type a caption: "; //prompts user to enter a caption
getline(cin, caption); //reads the complete line of caption from user
last_index = caption.size() - 1; //sets the last_index to the last character of caption
last_character = caption.at(last_index); //sets the last_character to the last character positioned by last_index
if ((last_character == '!') || (last_character == '?')) {} /* checks if the last character of the caption is either ! or ? and if this statement evaluate to true then this does not require any action */
else if (last_character == ',') { //checks if the last character of the caption is a comma
caption.at(last_index) = '.'; } //if the else if condition is true then replace that comma with a period .
else if (last_character != '.') { //checks if the caption does not end with ! ? , .
caption.push_back('.');} //append period to the caption . if above if else condition is true
else if ((last_index > 0) && (last_character == '.') && (caption.at(last_index - 1) == '.')) { //checks if the caption has two periods .
if ((last_index > 1) && (caption.at(last_index - 2) == '.')) {} //checks if the caption has three periods and does nothing if this is true
else { //if caption has two periods
caption.pop_back();}} //removes one period if caption has two periods .
cout << caption << endl;} //displays the caption
Explanation:
I will explain the above program with an example
Lets say user input the caption: I like pie
So
caption = " I like pie"
The first if condition if ((last_character == '!') || (last_character == '?')) evaluate to false because the last character of the caption is not an exclamation mark of a question mark. So the program moves to the next else if statement:
else if (last_character == ',') This statement is also false because the last character of the caption is not a comma. So the program moves to the next else if part.
else if (last_character != '.')
Now this statement evaluate to true because the last character of the caption is not a period . sign. So this part is executed. It has a statement:
caption.push_back('.');
Now this statement uses push_back() method which adds new character i.e. period '.' at the end of the caption string, increasing its length by one.
So the output of the program is:
I like pie.
If the caption = " I like pie!" then this if ((last_character == '!') || (last_character == '?')) condition executes and since it does nothing {} so the caption remains as it is and the output is:
I like pie!
If the caption = "Coming soon…" then this else if ((last_index > 0) && (last_character == '.') && (caption.at(last_index - 1) == '.')) condition executes which checks if the caption has two period. When this condition evaluates to true then the statement inside this else if condition executes which is: if ((last_index > 1) && (caption.at(last_index - 2) == '.')) and this checks if the caption has three periods. Yes the caption has three periods so it does nothing and the caption remains as it is and the output is:
Coming soon…
However if the caption is Coming soon.. with two periods then the else part inside else if ((last_index > 0) && (last_character == '.') && (caption.at(last_index - 1) == '.')) condition executes which is: caption.pop_back(); and this removes one period from the caption and the output is:
Coming soon.
The screenshot of the program and its output is attached.
