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

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

Which operator can not be overloaded?

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?

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

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?

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

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?

 _______ remain in memory even when all objects of a class have been destroyed

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

Which of the following may not be an integral part of an object?

Which one of the following terms best represents the statement given below, ” Hiding details of an object from the other parts of a program”

A class can be identified from a statement by -------------

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

__________ satisfy the condition of polymorphism

The process of hiding unwanted details from users is called __________

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?

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

Using encapsulation we can achieve

What is true about function templates?

For classes with common behavior, you can save effort by placing the common behavior in a __________
