Create a cpp File - Separate the Interface from the Implementation

The video tutorial explains the separation of interface and implementation in C programming. It guides viewers through creating separate files for interface and implementation, using header guards, and following naming conventions for classes and functions. The tutorial also covers finalizing header files with function prototypes and addresses common errors and debugging techniques.

What is the main purpose of separating the interface from the implementation in programming?

• To reduce the file size

• To allow multiple users to edit the code simultaneously

• To improve code readability and maintainability

• To increase execution speed

What is the role of a header file in C programming?

• To execute the program

• To compile the code

• To store the main logic of the program

• To declare function prototypes and include necessary libraries

Why are header guards important in C programming?

• To allow dynamic memory allocation

• To speed up the compilation process

• To prevent multiple inclusions of the same header file

• To enhance the security of the code

What must be added before any function in the implementation file to ensure correct linkage?

• The file name

• The return type of the function

• The function parameters

• The name of the class followed by ::

What should be left in the header file after moving the implementation to a C file?

• The main logic of the program

• The full function definitions

• The variable declarations

• Only the function prototypes

What is a common error when a function is not declared in the correct scope?

• The function is not recognized

• The function executes twice

• The program runs slower

• The program crashes

What should you check if you encounter an error stating a variable is not declared?

• Recompile the program

• Check if the class name is correctly prefixed

• Ensure the variable is initialized

• Verify the variable type
