As the error suggests, you can only have one definition of the main function in any cpp file in your project.

Since it looks like you’re on the Axe Game section, you just need to delete the definition of the main function in Bienvenue.cpp or delete that file from your project.

Thank you very much.
I completely deleted the “Bienvenue” file ^^

Glad I could help!

For some added context. The reason why you can only have one definition of the main function is because the compiler uses that function as the starting-point of your program, if you have the main function defined in multiple places then it doesn’t know where to start and throws an error.
