Chapter 9.9, Problem 9.14CP

Program Plan Intro

Purpose of “new” operator:

The main purpose of the “new” operator is to dynamically allocate memory. Dynamic memory allocation is process where an individual chunk of memory space is allocated by the compiler that is sufficient for the storage of variables.

Purpose of “delete” operator:

The purpose of “delete” operator is to clear or free the memory that was allocated using a “new” operator. The allocated memory gets de-allocated when “delete” operator is used.

Example:

//null pointer declaration

int *myptr = nullptr;

//dynamic allocation of memory

myptr = new int;

//free the memory allocated

delete myptr;

//assign the value to be null

myptr= nullptr;
