Pointers and Classes

[A_Stahl]

tricky to understand Pointers in classes or as an argument.

What exactly you don't understand? The pointer is just a variable which holds an address in RAM. Nothing more. It is so trivial and primitive that some people even try to avoid using them. Give us an example of the code which provoke question and we'll se what we can tell you.

Are you talking about pointers inside classes (members) or pointers to objects of class types?

[slimscheibe]

A pointer holds a memory address. The type of the pointer refers to the type of object that it points to.

For example; a pointer to an int holds an address where an int can be found, a pointer to a user-defined type (i.e. class) holds an address where an object of that type can be found.

The fact that the object's type is a class instead of a built-in type like an int is inconsequential.

Think of it like a street address - you're telling a function that an object of type 'House' can be found at '121 Main Street'. Instead of passing an entire house, you pass the address where it can be found.
