How to do it...

In the following code, we declare a simple Object class, then construct an instance of it using the new operator:

class Object 
{ 
  Object() 
  { 
    puts( "Object constructed" ); 
  } 
  ~Object() 
  { 
    puts( "Object destructed" ); 
  } 
}; 

// Invokes constructor 
Object * object = new Object(); 

// Invokes deconstrctor 
delete object; 

// resets object to a null pointer
object = 0;
