Example of logging allocations

ex.cpp

#include <iostream>

int main(int argc, char *argv[])
{
  int * ip = new int;
  std::cout << "Allocated at " << (unsigned long)(ip) << "\n";

  // do something with object, e.g.
  *ip = 4;
  
  std::cout << "Deallocating " << (unsigned long)(ip) << "\n";
  delete ip;
  
  return 0;
}
