Question: 1 / 565

What is the primary benefit of using the inline keyword for functions outside of classes?

To make the function virtual.

To reduce the binary size.

To eliminate function call overhead.

The main advantage of using the inline keyword for functions outside of classes is to eliminate function call overhead. This means that the function will be directly inserted into the calling code instead of creating a separate call. This can improve performance by reducing the time and space required for function calls. Option A is incorrect because the inline keyword does not make a function virtual. Option B is incorrect because the inline keyword may actually increase binary size due to duplicating the code in multiple places. Option D is also incorrect because the inline keyword does not automatically make a function const – it only suggests to the compiler to do so. Therefore, the primary benefit of using the inline keyword is to eliminate function call overhead.
