Hi experts!

In many of the books i have read describe that " C++ objects communicate each other",and this concept is the one which confuses me most.

Can anybody explain me How this communication between objects is done with "theoriotical" and "code example"
or else give me link which expalins me about this concept


Thanks in advance

Pratically they communicate with each other by calling member functions.

Example:

class Door
{
public:
   open(); // message to open the door.
};

class Car
{
   Door leftDoor; // door object, for left door
   Door rightDoor;, // door object, for right door
public:
   openLeftDoor() {    // message to open the left door of the car
      leftDoor.open(); // internally it is passing the message to the door object to open it.
   }
   openRightDoor() { // message to open the right door of the car
      rightDoor.open();
   }
}

C++ objects do NOT communicate with each other.  Let's settle that.  There is no built-in feature in C++ to do this.
