why didn't it take the ascii value of the number within the ' ' ? for example if we put char ch = '97'; and we check it using the isalpha(ch), doesn't it understand that 97 is the ascii value of a and thus it returns a non zero value? I'm confused a little bit here.

Is there a way to input something, and have it check what you input?
