If you have no knowledge of C, stop fixing code, start learning C and programming. Proceed with smallest possible applications, for exercises, until you achieve good confidence. This is the best advice I can give you. If you don’t want to follow my advice, I must warn you: you will loose a lot of time and will get a lot of frustration.
