14. What is an object in C++? Group of answer choices An object is a class declared entirely within the body of another class or interface. An object is an extensible program-code-template for creating classes, providing initial values for state (member variables) and implementations of behavior (member functions, methods) Anything that may be apprehended intellectually. An object refers to a particular instance of a class where the object can be a combination of variables, functions, and data structures. Anything that is visible or tangible and is relatively stable in form.
Write the program of object oriented programming c++. Declared Rectangle(Data Members: Length and width) as a friend class of Square(Data Member: int side). Thus now, all the functions of Rectangle can directly access any private member of Square.In the main function, the first statement created an object 'square' of the class Square, thus calling its constructor and assigning 5 to its data member side.The second statement in the main function created an object 'rectangle' of the class Rectangle.In the third statement, 'rectangle' called the function shape() with the object of the class Square passed as its argument. In the 'shape()' function, the value of 'side' (private data member of Square) was assigned to length and breadth. The fourth statement called the function 'getArea' of the class Rectangle.
