Dangling pointer is a pointer which is pointing to the destroyed object or which does not have proper address. A pointer should be intialized to zero once it is freed after allocating memory to that pointer. Ex: main() { int *ptr; ptr=(int *)malloc(sizeof(int)); .................. ................. free(ptr); ptr=0; } All pointers should be initialized to zero when declaring them, otherwise we can call it as dangling pointer.
