Pointer: Pointer is a special type of variable to store the address of the memory location. 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 address 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>; Example for pointer variable declaration: //definition of pointer variable int ptrvar; Where, int is the variable type. ptrvar is the pointer variable name. Note: When the symbol “&” is placed prior the pointer variable, it will hold address of the pointer variable. When the symbol “*” is placed prior the pointer variable, it will hold the value of the pointer variable.

Question

Chapter 10.5, Problem 10.1CP

Program Plan Intro

Pointer:

Pointer is a special type of variable to store the address of the memory location.

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 address 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>;

Example for pointer variable declaration:

//definition of pointer variable

int ptrvar;

Where,

int is the variable type.

ptrvar is the pointer variable name.

Note:

When the symbol “&” is placed prior the pointer variable, it will hold address of the pointer variable.

When the symbol “*” is placed prior the pointer variable, it will hold the value of the pointer variable.
