Valid, but worthless syntax in switch-case?

Question

Through a little typo, I accidentally found this construct:

int main(void) {
    char foo = \'c\';

    switch(foo)
    {
        printf(\"Cant Touch This\\n\");         


        

Answer 1

Assuming you are using gcc on Linux, it would have given you a warning if you're using 4.4 or earlier version.

The -Wunreachable-code option was removed in gcc 4.4 onward.
