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.

Expert Solution
Check Mark
Step 1: Algorithm for Checking if a Number Contains the Digit 5
  1. Start.
  2. Initialize an integer variable num to store the user input.
  3. Display the message "Enter a positive integer."
  4. 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.
  5. 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.
  6. Call the containsDigit5 function with the num as the argument.
  7. If the function returns true, display the message "The number contains the digit 5."
  8. If the function returns false, display the message "The number does not contain the digit 5."
  9. End.
