How to return a char function in C prog? [closed]

I am not sure how to store the return char function so I can return it to be used in the main function,

char process_3 (int step_2)
{
  if (step_2 % 2 == 0)
  {
    printf ("A");
  }
  else if (step_2 % 3 == 0)
  {
    printf ("F");
  }
  if (step_2 % 5 == 0)
  {
    printf ("K");
  }
  else if (step_2 % 7 == 0)
  {
    printf ("P");
  }
  if (step_2 % 11 == 0 || step_2 % 13 == 开发者_如何学编程0)
  {
    printf ("T");
  }
  else
  {
    printf ("Z");
  }
  return process_3;
}

Try this:

char process_3 (int step_2)
{
    char c;
    if (step_2 % 2 == 0)
    {
        c = 'A';
    }
    else if (step_2 % 3 == 0)
    {
        c = 'F';
    }
    if (step_2 % 5 == 0)
    {
        c = 'K';
    }
    else if (step_2 % 7 == 0)
    {
        c = 'P';
    }
    if (step_2 % 11 == 0 || step_2 % 13 == 0)
    {
        c = 'T';
    }
    else
    {
        c = 'Z';
    }
    return c;
}

You can assign chars to a variable using single quotes and return them from functions as well.

A character literal in C is enclosed in single quotation marks, like this:

'a'

To return a character from your function you'd write a return statement with the character literal. For example:

if (step_2 % 2 == 0)
    return 'A';

This is very basic C stuff. I suggest Googling some tutorials and/or getting a book on C to learn the basics of the language.
