We don't do homework. If you get stuck and need help we are willing to help you.
Show your work and where you're stuck.

So did you have an actual question, besides "how do I code this?". If you have no idea how to start, talk to your teacher.

When answering a question please:

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

Here is one place to start : cplusplus.com : fgets[^]. The sample code shows you how to open a file, read from it, and close it. That's what you need to do to read the data from the file. This function - cplusplus.com : atoi/[^], can be used to convert text to an integer value. From there, you will need to add code to perform the logic described in your problem statement.

I recommend that you read the documentation for many of the functions listed with atoi because they might also be of use to you.

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

If you are having problems getting started at all, then this may help: How to Write Code to Solve a Problem, A Beginner's Guide[^]
