First, if this is a C problem, you should have posted it in the C forum. So, please tell us if it is, in which case, it can be moved to the appropriate forum.

Second, we don't just solve people's assignments / exercises for them. You have to show that you are making efforts to solve the problem. What have you tried? What are the specific problem(s) you encountered?
