Thread: integer and char, convert?

Maybe this is a simple question, maybe it can't be done, I don't know

I've got a simple menu. The user should be able to input either a integer, to go back to the previous menu, or input a filename, which makes a mp3file to be played. How should this be done?

The best way to deal with this is to accept the input as a string and call the following function

I also assume that your filename shouldn't be allowed to have spaces in it

Code:

#include <ctype.h> // put at the top

// returns true if the string should be used as a mp3filename
bool TranslateInput( const char* input )
{
    for (int i = 0; input[i] != 0; i++)
         if ( !isalpha(input[i]) || !ispunct(input[i]) )
              return false;
    return true;
}
