Switch statement using or

Question

I\'m creating a console app and using a switch statement to create a simple menu system. User input is in the form of a single character that displays on-screen

Answer 1

Just use tolower(), here's my man:

SYNOPSIS
#include ctype.h

   int toupper(int c);
   int tolower(int c);

DESCRIPTION toupper() converts the letter c to upper case, if possible.

   tolower() converts the letter c to lower case, if possible.

   If c is not an unsigned char value, or EOF, the behavior of these
   functions is undefined.

RETURN VALUE The value returned is that of the converted letter, or c if the conversion was not possible.

So in your example you can switch() with:

switch(tolower(menuChoice)) {
    case('q'):
        // ...
        break;
    case('s'):
        // ...
        break;
}

Of course you can use both toupper() and tolower(), with capital and non-capital letters.
