C++ Developer - Separate Compilation

This video tutorial covers the concepts of data members, methods, and the constant keyword in C++. It introduces the topic of separate compilation, explaining how to organize code into header and implementation files. The tutorial demonstrates refactoring code to separate class definitions and implementations, and discusses the importance of include guards for preventing multiple inclusions of header files. A challenge is presented to add a member function to a class and refactor the code accordingly.

What is the primary purpose of using the 'constant' keyword in C++?

• To prevent changes to data members

• To make functions run faster

• To allow variables to change their values

• To increase the speed of the program

What is the main advantage of separate compilation in C++?

• It allows for faster execution of programs

• It reduces the size of the executable file

• It simplifies the syntax of the language

• It helps in organizing code into reusable components

In C++, what is the typical file extension for a specification file?

• .cpp

• .c

• .hpp

• .h

What is the first step in refactoring code to use separate compilation?

• Compile the program

• Create a new main file

• Delete all existing files

• Move class definitions to a header file

Why is it important to use include guards in header files?

• To make the code run faster

• To allow multiple inclusions of the same file

• To ensure the header file is included only once

• To prevent syntax errors

What does the scope resolution operator (::) do in C++?

• It initializes a variable

• It defines a new class

• It ends a statement

• It specifies that a function belongs to a class

What is the purpose of the 'pragma once' directive?

• To define a new class

• To speed up the compilation process

• To ensure a file is included only once

• To include a file multiple times

What is the benefit of using member functions over global functions?

• They are easier to write

• They use less memory

• They have access to private data members

• They are faster

In the challenge, what was the new member function added to the House class?

• print

• calculateArea

• getWindows

• setColor

What is the correct way to call a member function in C++?

• functionName()

• objectName.functionName()

• className::functionName()

• functionName::objectName()
