Chapter 9, Problem 4RQE

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.

Consider the following statement:

//definition of pointer variable

int *ptrvar;

Here, the variable “ptrvar” is defined to a pointer variable of integer data type. So, it can store the address of an integer variable.
