I thought passing by reference was risky though?

I remember we had a similar question about function arguments, and I think "by reference" was a key point in that discussion.

I feel like "by value" is definitely one of the options, but "by void" seems off to me.

I'm pretty confident I know the answer to this one. The correct options are A (by value) and B (by reference). Passing by pointer is a bit more advanced, so I don't think that's the right approach for this basic question.

Okay, I've got this. You can pass arguments to functions in a few different ways - by value, by reference, or by pointer. Passing by value means you're just copying the value of the argument, while passing by reference or pointer allows you to modify the original variable.

Hmm, I'm a little unsure about this one. I know you can pass arguments by value, but I'm not totally clear on the difference between passing by reference and passing by pointer. I'll have to think this through a bit more.

This is a pretty straightforward question. I think the answer is either A or B - you can pass arguments to functions by value or by reference.

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.

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