Program Plan Intro

Pointer:

Pointer is a special type of variable to store the address of the memory location, which can be accessed later.

• If an asterisk “*” operator is present before the variable, then that variable is referred as pointer variable.
  • It is also called as dereferencing or indirection operator.
• Pointer is just a type of variable that stores the addresses of other variables.
• Using pointers, the address of a variable can be accessed and the data stored in that variable can be retrieved.

Syntax of pointer variable declaration:

<variable-type> *<variable-name>;

Usage of pointers to structures:

The usage of pointers to structure is same as declaring a pointer variable.
