I know that this problem is very easy, because I’ve encountered this problem when I was a first year college student using C language, but whyyyy I can’t answer this simple problem during that exam, well the result is failed, (lol), because of that incident, and because of my stupidity I tried this problem into my own computer, then I got it right (sad). I’m working for almost 8 months as a junior programmer, but then I didn’t pass that exam. (I think, because I didn’t get any proper training at all, or maybe I’m just really stupid), well there is always another chance :P.
