switch case

[chrismiceli]

i have this code

#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>

void main() {
        char c;
        printf("Please make your treat selection:\n");
        scanf("%s",&c);
        c=toupper(c);
        switch(c)
        {
                case 'H':
                        printf("Beverage\nThat will be $2\n");
                        break;
        }
}

but if i changed 'H' to 'HE' my gcc compiler give me an error. could someone explain?

Probably because you are switching on a variable of type character which can only hold one character. You will probably want to use the String datatype.

edited original post. still errors.

Well, switch case allows you to use only integers, and character (which again are processed as integers internally) datatypes. 'H' is a character and "HE" is a string, so it wont work. You have to use if (strcmp(somevar, "HE") == 0) to check if the somvar contains "HE"
