I only learnt C++ but i think it should be the same.

Pointers are variables that points to another variable. It doesn't hold a value but the address of another variable.

You can view more example from howstuffworks

If you are doing an assignment, maybe you can state out the question so the skilled programmers here (i'm not included) can help you?

a pointer works like this :

int *iPointer;

int iVar=2;


There's two way to access a variable. if you do something like

printf("Here is iVar %d", iVar)

you'll see the value of iVar. 2

But you can also access the "memory address" of the variable. While it serves little purpose with two var, integer more so, it can be pretty important when you try to use dynamic data strucutres.

To see the memory adress of an object, you use &.


printf("Here is iVar %d", &iVar)

This would display something really different, the memory location of iVar.

so iPointer = &iVar would make the pointer "point" to the memory location of iVar. You can then access (read, modify) the value of iVar through iPointer.
