int* p;

int q;

However, in C#, the 

*

is

 distributive and the declaration

int* p, q;

creates two pointer variables. Thus, in C# it is the same as these two declarations:

int* p;

int* q;

This is an important difference to keep in mind when porting C/C++ code to C#.

The * and & Pointer Operators

Two operators are used with pointers: 

*

 and 

&

. The 

&

 is a unary operator that returns the 

memory address of its operand. (Recall that a unary operator requires only one operand.) 

For example,

int* ip;

int num = 10;

ip = #
