Show HN: I always wanted to learn C and make some app in “C”

I always wanted to learn "C" but never found an real-world application of what I cound make. On last Sunday, I needed to measure time of some tasks. So I wrote an terminal "Stopwatch" app. It's my first application in C programming language, probably it is stupid and not efficient. If you mind, let me know, so I can learn more about C in real world.
