The >= operator can be overloaded.

Suppose there is an object of type Person, which of the following can be considered as one of its attributes

An overloaded operator always requires one less argument than its number of operands

Which operator can not be overloaded?

Static variable can be initialized more than once

___________, which means if A declares B as its friend it does NOT mean that A can access private data of B. It only means that B can access all data of A

A generalization-specialization relation between classes are implemented using

Your chief Software designer has shown you a sketch of the new Computer parts system she is about to create. At the top of the hierarchy is a Class called Computer and under this are two child classes. One is called LinuxPC and one is called WindowsPC. The main difference between the two is that one runs the Linux operating System and the other runs the Windows System (of course another difference is that one needs constant re-booting and the other runs reliably). Under the WindowsPC are two Sub classes one called Server and one Called Workstation. How might you appraise your designers work?

Which of the following is the best approach if it is required to have more than one functions having exactly same functionality and implemented on different data types?

A non-virtual member function is defined in a base class and overridden in a derived class; if that function is called through a base-class pointer to a derived class object, the derived-class version is used

Suppose that the Test class does not have an overloaded assignment operator. What happens when an assignment a=b; is given for two Test objects a and b?

The statement objA=objB; will cause a compiler error if the objects are of different classes

a’A static member function can be called, even when a class is not __________

The return type of a constructor is of -------------

We achieve independence of internal implementation from its external interface through----------- 

The life of sub object is not dependant on the life of master class in ___________

Static variable can be initialized more than once.

C++ compiler does not allow to dynamically allocate memory for objects

What problem(s) may occur when we copy objects without using deep copy constructor?

Assume a class C with objects obj1, obj2, and obj3. For the statement obj3 = obj1 - obj2 to work correctly, if the overloaded - operator must

The find() algorithm

A member function having the same name as that of a class and a ~ sign with it is called,

If there is a pointer p to objects of a base class, and it contains the address of an object of a derived class, and both classes contain a nonvirtual member function, ding(), then the statement p->ding(); will cause the version of ding() in the _____ class to be executed

Classes like TwoDimensionalShape and ThreeDimensionalShape would normally be concrete, while classes like Sphere and Cube would normally be abstract

Which one of the following features of OOP is used to derive a class from another?

In order to define a class template, the first line of definition must be:

Suppose you have been given the following design, "A person has a name, age, address and sex. You are designing a class to represent a type of person called a patient. This kind of person may be given a diagnosis, have a spouse and may be alive". Given that the person class has already been created, what of the following would be appropriate to include when you design the patient class?
