And you *can* use sizeof on arrays :-).
Well at least in ANSI/ISO C. Haven't tried this on plan 9. :-)
On my mac I get 6 and 8.
#include <stdio.h>
char blah [] = "Hello";
char * blah2 = "There";
int main () {
printf("sizeof blah: %ld\n", sizeof(blah));
printf("sizeof blah2: %ld\n", sizeof(blah2));
}
