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>; 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 2 bytes will be added to the pointer variable “a” after incrementing it by “1”.

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>;

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 2 bytes will be added to the pointer variable “a” after incrementing it by “1”.
