yes,we can declare the object of one class into another class. The kind of relationship is called Containership or nesting. this is one of the best feature of c++ which allow inheritence and reusability.
for eg:
class alpha {.....};
class beta {....};
class gamma
{
alpha a;
beta b;
...
};


Creation of one object into another is very different from that of an independent object. Independent object is created
by cnstructors when declared with the arguments.
