To know whether the block of memory allocation fails, you can detect the failure through checking whether the pointer variable is null.

Avoiding Memory Leaks

When a programmer creates a memory in the heap and forgets to delete it, it creates a memory leak. To avoid having a memory leak, you should free the memory allocated on the heap when no longer needed. Always make sure to use the right operator (delete or delete []) to deallocate the memory.

If there is a memory leak, then the memory usage increases. This makes the limited memory resource very costly thus creating more problems later. The example below is a program to show a memory leak.

Syntax

#include <iostream.h>
