Its homework, besides you have a debugger don't you? Run the code, test tings out.

We would be able but will not do your homework for you.

Reread your course notes and / or a C++ tutorial. If you then still have a specific question, we will help.

yz ;-)

We don't do homework for you. Homework, exercises, tests are all designed to help you to cement the learning in your brain.

Whilst many of us can answer the questions, we would not be doing you any favours if we did.

Try it yourself using your course notes (or other research). If you get stuck then come back with your own suggestions and we can help you with specifics
We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
