firstly, I'm sorry for my bad english language becuase I can't speak English very well.
I have problem to create a class that take data base (i.e students names,ages,birthday) and I want this class to search for any name, also delete any item, add any item.
can you help me, please.

Hey, and welcome to these boards!

I need to know have you any experience with C++? Is this a course excercise - I don't want to give you a clever trick if you've not come across it yet.

What you need is the vector class, see here for it's function list: www.fredosaurus.com

This is a member of the STL (Standard Template Library) - it's a very useful class for creating dynamic arrays, ones which will grow and shrink to suit. You can pass it any object you want, and then you can add & remove them as you like, using the add() and erase() functions.

If it is an excercise, I'm not going to code it for you - the only way you'll learn is by doing it yourself. But I will help you if you have syntax errors & stuff. OK?
