Trivial: Was ist ein Pointer?

[Mirilin]

Zitat:

So what is a pointer? Simply put, a pointer is a variable that holds the address of anything in memory.
To concrete this definition, just keep in mind the following: everything used in an application is stored somewhere in the computer's memory, a pointer to that item simply points the program to that memory location. Because a pointer holds the address of another variable, it is said to point to that variable.
