A pointer pointing to an object that has been destroyed is called a Dangling pointer. main( ) { int *p ; int *fun( ) ; p = fun( ) ; printf ( "%d", *p ) ; } int *fun( ) { int a = 10 ; return ( &a ) ; } Here it appears that address of a would be collected in p and through *p we would be able to access 10. This however is not possible because by the time address of a is collected in p, a is already dead. So you have a pointer containing an address, and the object at this address is long dead. Thus p becomes dangling pointer.
