Hi

Someone was saying that an object can exist within an object. The discussion was about classes. I know that a class can exist within a class but don't get how an object can exist within some other object. Does it make any sense to you? Please let me know. Thank you.

Regards

An object exists within another object only when a class contains other objects or classes

class X

{

 public:

    int x;

}


int main()

{

   X h; // now h contains an instance of x

Yes.

class X

{

public:

int a;

};

class Y

{

public:

X x;

};

int main()

{

Y g;  //here object g contains x which is object of X

g.x.a=10;

}
