Hi GCC Help,
What is my confusion here? I am using gcc 4.1.2-14 on an i386 machine.
I don't know why I am getting a different value than I expect. Is
there a compiler flag I can use to make the expression evaluate
correctly according to my expectations? Thanks!
int main(char argc, char* agrv[]) {
unsigned short a;
unsigned short b;
a = 0xFFFF;
b = 0x3FC;
a = (a + 1) % b;
printf ("A is 0x%x\n", a);
// I expect the answer to be 0 and it is not! It is 0x100. Why is this?
a = 0xFFFF;
a = (a + 1);
printf ("A is 0x%x\n", a);
// I expect the answer to be 0 and it is.
a = a % b;
printf ("A is 0x%x\n", a);
// I expect the answer to be 0 and it is.
}
Best Regards,
Scott
