In C++, what does the `extern` keyword indicate when used with a function declaration?

The function is defined in another file
The function will not throw any exceptions
The function takes a variable number of arguments
The function returns an external type

The correct answer is: The function is defined in another file

The `extern` keyword in C++ is used to indicate that the function is defined in another file. This means that the function is declared in one file but defined in another file, allowing for code reusability and modularity. Option B is incorrect because `extern` has nothing to do with exception handling. Option C is incorrect because the `extern` keyword is used with function declarations, not definitions, and has no impact on the number of arguments a function takes. Option D is incorrect because the `extern` keyword does not specify the return type of a function.
