For Loop Continues Forever?

My code is exactly the same as the video, but the loop doesn't seem to stop when i becomes greater than 3.

I get a continuous stream of large numbers in my output, and finally an (lldb) at the end.

Here's my code:

#include <stdio.h>

int main()
{

    int many[] = {2, 4, 8};
    int sum = 0;
    for (int i=0; 1 < 3; i++) {
        sum += many[i];
        printf("i %d sum %d\n", i, sum);
    }
    return 0;
}

and here's the end of my output:

... i 135700 sum -492767949 i 135701 sum -492767949 i 135702 sum -492767949 i 135703 sum -492767949 i 135704 sum -492767949 (lldb)

Hi Allison, I edited your code with markdown so it is easier to read. I think your problem is you wrote '1 < 3', instead of 'i < 3'. Hope that fixes it!
