Program Plan Intro

Pointer:

Pointer, the name itself references the purpose of the pointer. Pointers point to a location in memory.

• 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, we can access the address of a variable; the data stored in that variable can be retrieved.

Syntax of pointer variable declaration:

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