#include <iostream> 
#include <new> 
using namespace std; 
 
int main() 
{ 
  int *p; 
 
  try { 
    p = new int; // allocate space for an int 
  } catch (bad_alloc xa) { 
    cout << "Allocation Failure\n"; 
    return 1; 
  } 
 
  *p = 100; 
 
  cout << "At " << p << " is the value " << *p << "\n"; 
 
  delete p; 
 
  return 0; 
}
