Hi all. I’m a beginner to C. And I am writing a program which updates a billing system. I just need any of you to help me check the coding I have made. And I do not have C software on this computer, so I have to do it in college. Please, my dateline is coming. This is the coding…. I would totally appreciate it if you do help me.
