Can't subtract in a for loop in C/Objective-C
- by user1612935
I'm going through the Big Nerd Ranch book on Objective-C, which takes you through some early C stuff. I've played with C before, and am pretty experienced in PHP.
Anyhow, I'm doing the challenges and this one is not working the way I think it should. It's pretty simple - start at 99, loop through and subtract three until you get to zero, and every time you get a number that is divisible by 5 print "Found one." Pretty straightforward. However, subtracting by three in the for loop is not working
#include <stdio.h>
int main (int argc, const char * argv[])
{
int i;
for(i = 99; i > 0; i-3){
printf("%d\n", i);
if(i % 5 == 0) {
printf("Found one!\n");
}
}
return 0;
}
It creates and endless loop at 99, and I'm not sure why.
