Someone help please ... struct node { int d; struct node *next; } struct node * create(int val) { struct node nd, *ndPtr; nd.d = val; nd.next = NULL; ndPtr = &nd; return ndPtr; } Is ndPtr a dangling pointer ???
Dangling pointer is a pointer which points to an object that no longer exists and your one is a classic case of the same. It points the local variable nd which does not exist when gone out of scope of create but it returns the pointer to nd.
then why it doesn't crash. I compile it with 2 different compilers and it doesn't crash why is that ???
It doesn't have to crash. It can trash the latest autovariable which is now using that memory, which can be a very subtle failure. Read up on automatic variables and scope.
