#include<iostream>
using namespace std;

int main()
{
  int* p=new int[2];
  p[0]=1;
  p[1]=2;

  cout<<p[1]<<" "<<&p[1]<<endl;
  cout<<endl;
  cout<<*p<<" "<<p<<endl;
  p++;
  cout<<*p<<" "<<p<<endl;

The memory manager is choking on your pointer 'p' because you incremented its value.

Check the enclosed code..

#include<iostream>
using namespace std;

int main()
{
  int* p=new int[2];
  p[0]=1;
  p[1]=2;
  cout<<p[0]<<" "<<&p[0]<<endl;
  cout<<p[1]<<" "<<&p[1]<<endl;
  cout<<endl;
  cout<<*p<<" "<<p<<endl;
  p++;
  cout<<*p<<" "<<p<<endl;
  p--;//set pointer back to its original …
