I was sure my for loop was broken because it kept running forever

Turns out I was incrementing the wrong variable inside the loop, so the condition was never met. I spent an hour staring at it before a friend spotted my mistake. Has anyone else done something that simple and felt completely stuck?

What variable were you trying to increment instead? I've definitely written 'i++' when the loop used 'x' and just sat there baffled lol. Those tiny typos are the worst.

Disagree, those little typos teach you to read your code twice which makes you a better debugger in the long run.

Wait, did you mean you wrote i++ when the loop variable was x? I've done the opposite before, like using the right variable name but spelling it wrong. One time I had a loop with "counter" and kept typing "count++" instead. It compiled fine and just ran forever. How do our brains just skip over those details after looking at code too long?

Ugh, those are the absolute worst (like when you're so sure the code is broken, but it's just your own tiny mistake). I swear the more you stare at it, the more invisible it gets.
