Answer:

Memory leak occurs when programmers create a memory in heap and forget to delete it. Memory leaks are particularly serious issues for programs like daemons and servers which by definition never terminate.

 
/* Function with memory leak */
#include 
 
void f()
{
   int *ptr = (int *) malloc(sizeof(int));
 
   /* Do some work */
 
   return; /* Return without freeing ptr*/
}
