referenes and pointers

[mehak]

what happens when we try to access the value at a NULL pointer position as in the following program

#include<iostream>
using namespace std;

int main()
{
   int *ptr = NULL;
   int &ref = *ptr;
   cout << ref;
}

You are basically de-referencing a null pointer, which will result in a segmentation fault error if you attempt to run the program.

Why didn't you just run the program and find out yourself?
