Hello, can anyone help me write this program? Write a program that asks the user to enter a letter between the letters a, b and q. If the user enters otherwise, warn and ask the user to enter one of these three letters again. The following operation must be performed for each letter entered by the user.
Input a: Receives a number from the user as the side of a square and then prints the perimeter of the square. And again ask the user to enter a letter between a, b and q. Input b: Receive a number from the user as the side of a square and then print the area of the square. And again ask the user to enter a letter between a, b and q.
Input q: Completely exit the program.

You have a secret error in your secret code.

Nobody is going to write your code for you. That's not helping you at all.

If you show the code you have and list the errors you're getting, we can help you fix those.

What about visiting some Learn C++ tutorial and start coding.

It is a homework which is solvable when you acquired the basic skills in coding.

Tip: install some IDE like Microsoft Visual Studio.

This could be done with a do while loop and a switch statement, something like:

C++

int main()
{
  char c;
  do
  {
    // ask the use to insert a character, assing it to 'c'
    switch(c)
    {
    case 'a':
      // ask the user to input the side of the square, compute the perimeter and output it
      break;
    case 'b':
      // ask the user to input the side of the square, compute the area and output it
      break;
    default:
     // if (c != 'q') warn the user about incorrect input
      break;
    }
  } while ( c != 'q');
 
}
