Pointer: Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable. An asterisk “” is also referred as indirection operator is used to dereferences the pointer. Adding a value to a pointer variable: When a pointer variable is added, it is similar to adding number of time the size of the pointer variable that is stored. Example: //declaring a pointer variable int a; //incrementing the pointer value by 1 a++; In the above snippet the pointer variable is incremented by “1” means, the size of the pointer variable is being increased in terms of their size. 1 2 = 2 Therefore, additional of 2 bytes will be added to the pointer variable “a” after incrementing it by one.

Program Plan Intro

Pointer:

Pointer will allow the user to indirectly access and manipulate the variable data contents. A pointer variable will hold the address of the data contents. If an asterisk “” operator is present before the variable then that variable is referred as pointer variable. An asterisk “” is also referred as indirection operator is used to dereferences the pointer.

Adding a value to a pointer variable:

When a pointer variable is added, it is similar to adding number of time the size of the pointer variable that is stored.

Example:

//declaring a pointer variable

int a;

//incrementing the pointer value by 1

a++;

In the above snippet the pointer variable is incremented by “1” means, the size of the pointer variable is being increased in terms of their size.

1 2 = 2

Therefore, additional of 2 bytes will be added to the pointer variable “a” after incrementing it by one.
