Our C++ questions comes with the detailed explanation of the answers which helps in better understanding of C++ concepts.

C++ Questions & Answers focuses on “Modularization and Interfaces” along with answers, explanations and/or solutions:

Q 1. which of the following is used to implement the c++ interfaces?
A. absolute variables
B. abstract classes
C. constant variables
D. default variables

Show Answer

Answer:-B. abstract classes

Explanation

Abstract classes in C++ are purposely defined for making base classes containing atleast one virtual function which can be overloaded on inheritance, which means single function name for different sub-classes, hence acts as an interface.

Q 2. What is the ability to group some lines of code that can be included?
in the program?
A. specific task
B. program control
C. modularization
D. macros

Show Answer

Answer:-C. modularization

Explanation

Modularization is also similar to macros but it is used to build large projects.

Q 3. How many types do functions fall depends on modularization?
A. 1
B. 2
C. 3
D. 4

Show Answer

Answer:-B. 2

Explanation

There are two types of functions. They are program control and specific task.

Q 4. How many types of modularization are there in c++?
A. 1
B. 2
C. 11
D. 12

Show Answer

Answer:-B. 2

Explanation

There are two types of modular programming. They are interface and implementation.

Q 5. What does the client module import?
A. macro
B. records
C. interface
D. instance

Show Answer

Answer:-C. interface

Explanation

Because they access the functions in the module user interface.

Q 6. Identify the correct statement.
A. c++ does have built-in interfaces
B. c++ does not have built-in interfaces
C. c++ have no concept of interfaces
D. c++ does have built-in interfaces & classes

Show Answer

Answer:-B. c++ does not have built-in interfaces

Explanation

Unlike other programming languages like Java and others, C++ has no inbuilt interfaces.

Q 7. What is similar to the interface in c++?
A. methods
B. pure abstract class
C. instance of a class
D. methods & instance of a class

Show Answer

Answer:-B. pure abstract class

Explanation

Pure abstract classes in C++ are a type of interface because it contains only abstract member functions and no data or concrete member functions.

Q 8. Which of the following implements the module in the program?
A. header files
B. macro
C. macro & header files
D. interfaces

Show Answer

Answer:-A. header files

Explanation

We can include the group of code by using the #include header file.
