Question
Create a C++ file. Prompt the user for a positive integer, validating the input until the user enters a positive integer. If the number contains the digit 5 at any position, then print The number contains the digit 5. else print The number does not contain the digit 5.

Step 1: Algorithm for Checking if a Number Contains the Digit 5
- Start.
- Initialize an integer variable num to store the user input.
- Display the message "Enter a positive integer."
- Repeat the following steps until a valid positive integer is entered:
a. Read the user input into the variable num.
b. If the input is not an integer or is less than or equal to 0, clear the input stream, ignore any remaining characters, and display the message "Invalid input. Please enter a positive integer."
c. Otherwise, exit the loop. - Define a function containsDigit5 that takes an integer number as a parameter.
a. Initialize a while loop with the condition that number is greater than 0.
b. Inside the loop, check if the last digit of number (i.e., number % 10) is equal to 5.
c. If the last digit is 5, return true to indicate that the number contains the digit 5.
d. If not, divide number by 10 to remove the last digit and continue the loop.
e. If the loop completes without finding a 5, return false to indicate that the number does not contain the digit 5. - Call the containsDigit5 function with the num as the argument.
- If the function returns true, display the message "The number contains the digit 5."
- If the function returns false, display the message "The number does not contain the digit 5."
- End.

The code must then output the results of the multiple dice rolls. For line 1 **the numbers in brackets are the results of the multiple dice roll while the last number is the sum of the throws for the first die As you can see for the first line everything adds up correctly as the results of the dice (in brackets) are summed up correctly (last number) For the second row and all other following rolls, the code adds the rolls of the new dice and the result of the previous sum to get the new sum. This should not happen, I want the sum of each rows to be displayed on the end of each line The correct code should be display **please don't output comment [2] - [4 ]-[5] - 11 //dice rolled 3 times and sum is 11 [1] - [1 ]-2 //dice rolled 2 times with sum 2arrow_forwardcreate a new file in c++. In this lab, you will add some more functionality to the program. Use loops to keep running the program until the user chooses the exit condition (X or x). When dividing, use a loop to validate user input, making sure the denominator (second number) is not zero. If the user enters a 0 for the second number, display an error message and ask them again. A) Add two numbersB) Subtract two numbersC) Multiply two numbersD) Divide two numbersX) Exit program The program should: display a "hello" message before presenting the menu display the menu prompt user for selection accept either uppercase or lowercase for selection display error message if invalid selection is made (example: E) display the selection back to the user prompt for two numbers perform the operation and display the results use loop for input validation of second number during division display error message for division when second number is 0 after displaying result, use loop to…arrow_forward
