I am new to C programming. I have a very big program about 9000 lines which in turn depends on lots of other functions and programs.
I need to make some enhancements to that program and change some functionality.
Can somebody please guide me,
what should be my approach?
How should I start ?
How do I know what all programs use this program and whereall the changes are to be made?
I know I am vague but I myself am confused about the whole thing? please help.
