dangling pointer : Dangling pointers in computer
programming are pointers that do not point to a valid
object of the appropriate type. Dangling pointers arise
when an object is deleted or deallocated, without modifying
the value of the pointer, so that the pointer still points
to the memory location of the deallocated memory.

memory leak:A memory leak in computer science is a
particular type of unintentional memory consumption by a
computer program where the program fails to release memory
when no longer needed.
ex:
void f(void)
{
void* s;
s = malloc(50); /* get memory */
return;
}
//control comes out w/o freeing the memory....
