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?

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

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

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

Which of the following are an advantage of OOP?

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?

Given the following class class Base{ int Age=33; } How you can improve above class with respect to accessing the field Age?

What is true about function templates?

Identify which of the following overloaded operator function’s declaration is appropriate for the given call? Rational_number_1 + 2.325 Where Rational_number_1 is an object of user defined class Rational_number

We can use "this" pointer in the constructor in the body and even in the initialization list of any class if we are careful,

The compiler won’t object if you overload the * operator to perform division

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?

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?

Identify which of the following overloaded operator function’s declaration is appropriate for the given call? Rational_number_1 + 2.325 Where Rational_number_1 is an object of user defined class Rational_number

A static member function cannot be declared

________ is/are used to access information hidden within an object?

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?
