[c-prog] Help with SWITCH statement

[ayyaz]

Hello,

I need help in understanding the switch statement in C.

Why does the following code either display 'RED' or 'WHITE' when I enter 
'r' or 'w'?

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

int main(void)

{
     char choice;
     switch (choice = getchar()) {
     case 'r':

     case 'R':
         printf("RED");
         break;

     case 'w':

     case 'W':
         printf("WHITE");
         break;
     }

}




Should it not only output 'RED' or 'WHITE' when you enter 'R' or 'W'?

Thanks,
