Hello,
When I compile the following 5lines of code with `gcc -Wall -pedantic', I
get no warnings or any errors. However when I run the compiled
program I get the error: Floating point exception .
Anyone knows what I should fix ? I already tryd the different
storage types float, etc.. But then gcc complains warning: long int
format, int arg... etc... ?
I am using gcc version: 2.95.4
#include <stdio.h>
int main(void) {
int red = 0;
int green = 128;
int blue = 0;
printf("%d %d %d\n", (100 / (256 / red)),
(100 / (256 / green)), (100 / (256 / blue)));
return 0;
}
Thnkx.. J.

With red = blue = 0, you're having two divisions by zero. That won't
fly...
