Most of what you need to know about the new keyword

newkeyword.cpp

// BASIC EXAMPLE OF NEW KEYWORD IN ACTION


Cars *benz = new Cars();

// the delete keyword can be placed in the destructor
delete benz; 


// EXAMPLE 2;
// suppose we have an array of pointers ponting to a class
Car* smallcars[10];

// we can use the new keyword to create objects of the class
smallcars[0] = new Car;

// or suppose the Car class had other derived classes
// eg: Benz, Yoyota

smallcars[1] = new Benz;
// accessing a function
smallcars[1] ->hoot(); // BEEEEEP !!!!!

smallcars[2] = new Toyota;
smallcars[2] ->hoot(); // HOOOOONK!!!!


// THE DESTRUCTOR  DELETING THE OBJECTS AND THE ARRAY OF POINTERS
Car::~Car(void) {

    // deleting the objects
    for (int i = 0; i < 6; i++)
    {
        delete smallcars[i];
    }
  
  delete[] smallcars;//delete the array of pointers
  

}
