Passing by pointer? That's like trying to hand someone a ghost. Good luck with that one.

By void? Really? I guess you could just toss the function a big ol' pile of nothing and see what happens.

I'm going with B) by reference. It's the most common way to pass arguments to functions, and it allows you to modify the original values.

I prefer passing arguments by reference as well. It makes the code more efficient.

Hmm, I'm pretty sure it's either A) by value or B) by reference. C) by pointer sounds like it could work, but I'm not 100% sure.

Yeah, passing arguments by pointer allows the function to directly access and modify the original value.

Passing arguments by reference means the function can modify the original value.

I think passing arguments by value is when a copy of the value is passed to the function.

I think the correct answer is B) by reference. You can pass variables to functions and modify them directly.

Passing arguments by void doesn't make sense, void is used for functions that do not return a value.

By passing arguments by value, a copy of the variable is created and any changes made inside the function won't affect the original variable.

I think passing arguments by pointer is also a valid option, you can manipulate the memory address of the variable.

Definitely by value or by reference. Passing by pointer is a bit more advanced, and passing by void just doesn't make sense.
