- D. None of the mentioned Discuss
- 5. What is meant by pure virtual function?
Options- A. Function which does not have definition of its own.
- B. Function which does have definition of its own.
- C. Function which does not have any return type.
- D. None of the mentioned Discuss
- 6. Where does the exceptions are used?

Correct Answer: It will have certain data types to be fixed.
Explanation:
In the template specialization, it will make the template to be specific for some data types.
Correct Answer: A template is a formula for creating a generic class
Correct Answer: 3
Explanation:
There are three types of constructor in C++. They are Default constructor, Parameterized constructor, Copy constructor.
Correct Answer: create a hierarchy of classes
Correct Answer: Function which does not have definition of its own.
Explanation:
As the name itself implies, it have to depend on other class only.
Correct Answer: Exceptions are used when postconditions of a function can be satisfied.
Correct Answer: outside the regular code
Correct Answer: both a & b
Explanation:
new and delete operators are mainly used to allocate and deallocate
during runtime.
Correct Answer: Exception object is created only if an error actually happens
Explanation:
If an error occurs in program, then only exception object is created otherwise, It will not be created. So it?s expensive to use in the program.
Correct Answer: namespace std
Explanation:
:As these are standard exceptions, they need to be defined in the standard block, So it is defined under namespace std.
