Learn and Master C Programming - Creating A C++ Program That Uses Our C Library

The video tutorial guides viewers through opening a previous solution in Visual Studio, creating a new C project, and setting up project dependencies. It addresses common compilation errors related to unresolved external symbols and demonstrates how to use 'extern C' to ensure compatibility between C and C++ code. The tutorial concludes with a successful compilation and execution of both C and C++ projects using a shared library.

What is the purpose of identifying the active project in Visual Studio?

• To lock the project from further edits

• To highlight the project with the most errors

• To determine which project will be compiled first

• To set the project that will run when debugging

When creating a new C project in Visual Studio, what is the significance of setting it as the active project?

• It allows the project to be deleted

• It ensures the project is the default for running and debugging

• It prevents other projects from being modified

• It automatically compiles the project

Why is it necessary to set the include directory path when adding a library to a C++ project?

• To prevent the library from being deleted

• To ensure the library is the active project

• To allow the library to be edited

• To enable the project to compile without errors

What is the main issue caused by name mangling when linking C and C++ projects?

• It makes the project files unreadable

• It causes the project to run slower

• It results in unresolved external symbol errors

• It prevents the project from being saved

How can you prevent the C++ compiler from decorating function names when linking with a C library?

• By recompiling the library

• By renaming the function

• By using the keyword 'extern C'

• By using the keyword 'static'

What is the result of successfully resolving name mangling issues in a project?

• The project will run but with errors

• The project will compile successfully without errors

• The project will compile with warnings

• The project will not compile

What is the role of 'extern C' in a C header file?

• It makes the header file read-only

• It prevents the header file from being included

• It ensures the functions are compiled as C functions

• It allows the header file to be ignored
