Address Operator &

• & when applied to a variable produces the address of that variable.

  int x;
  
  int *pt;
  pt = &x;
  

• The first line defines the variable x. It is in a specific location in memory, say at 9640 (byte position).

• The second line defines a pointer variable of type int.

• The last line assigns pt to hold the value of the address of x. I.e., pt contains the value 9640. We say pt points to x.
