Answer:

A memory leak is a common and dangerous problem. It is a type of resource leak. In C language, a memory leak occurs when you allocate a block of memory using the memory management function and forget to release it.

#include<stdio.h>
#include<stdlib.h>
int main ()
{
    char * pBuffer = malloc(sizeof(char) * 20);
    /* Do some work */
    return 0; /*Not freeing the allocated memory*/
}

Note: once you allocate a memory than allocated memory does not allocate to another program or process until it gets free.
