edit: Spellings.
Thank you for the feedback. Some of the programs here are coded 4 years ago, when I had just started learning C++ and I never revisited them. At that time, I was in university, and this repo was to attract recruiters for internship. I got the job later, and kind of ignored to correct problems. I am sure if these are ran with strict compiler flags there would be many more issues. I will get around and fix it sometime soon.
