  Tutorial: C and Cpp Programming in C and Cpp C++ Functions Tutorial

This tutorial explains C++ functions. Functions make things a lot easier and a lot simpler, so you'd better understand them!

Tutorial Details:

Pointers in C++

1. What's a pointer?
Pointers can be very confusing, and initially hard to understand. They're even harder to explain. I will do my best though.

Imagine a pointer as being a cursor (like your mouse pointer). If it is assigned to a variable, it will be pointing to that variable. So whenever you call it, it sends you to that variable.

That was a simple explanation, though not a complete one. In truth, pointers point to the memory address of a variable. Imagine the memory is a room, and there's a TV on top of the table. If the TV was a variable, and you had a pointer to it, the pointer wouldn't say "TV". It would say "On top of the table". I hope things are not too confusing.

2. Using Pointers
You define a pointer using a (*) before the name. For example:
int *intptr;

To make the ptr point to something, you have to give it the ADDRESS. To get a variable's address in memory, use &.
