///C Programing Project\\ GCC Compiler
I would like the program to become more real world useful, I am open to your ideas(I was thinking some sort of a sports scoreboard program). This question seems to never get answered, so I decided to shorten the question for the tutors.. All I need is someone to give me ideas, and modify the code so it's useful for a real world situation.
Thanks
