Learn and Master C Programming - Creating Your First Library Project (.LIB)

This video tutorial guides viewers through creating a static library project in Visual Studio. It covers setting up the project, adding header and source files, compiling the project, and understanding the differences between library and executable files. The tutorial also demonstrates implementing a function and exposing it through a header file for use in other projects.

What type of project should be selected to create a static library in Visual Studio?

• Win32 Console Application

• Win32 Project

• DLL Project

• Executable Project

What is the purpose of adding '#pragma once' in a header file?

• To execute the file

• To compile the file separately

• To prevent multiple inclusions of the file

• To include the file multiple times

What is the main difference between a library file and an executable file?

• Executable files are used to store reusable code

• Library files are used to store reusable code

• Executable files cannot be run

• Library files can be executed directly

Why is it unnecessary to include a main function in a static library?

• Because it is not needed for compilation

• Because it is not a standalone application

• Because it is only for testing

• Because it is automatically included

What should be done if a function in the library uses 'NULL'?

• Remove the function

• Ignore the warning

• Include a standard IO header file

• Define NULL manually

Where should the function prototype be placed for external use?

• In the project settings

• In the source file

• In the library header file

• In the main function

What is the purpose of the main header file in a library?

• To store all source code

• To expose interfaces and prototypes

• To compile the library

• To execute the library
