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. Pointer to constant: When an address of a constant item is passed to a pointer such that no modification can be made to that variables pointer to constants can be used. Example: //definition of pointer to constant variable const int *ptr; Explanation: In the above definition, the variable “ptr” is declared as constant and any change made will not be accepted by the compiler.

Question

Chapter 9, Problem 61RQE

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.

Pointer to constant:

When an address of a constant item is passed to a pointer such that no modification can be made to that variables pointer to constants can be used.

Example:

//definition of pointer to constant variable

const int *ptr;

Explanation:

In the above definition, the variable “ptr” is declared as constant and any change made will not be accepted by the compiler.
