Why would I want to use inlining?

Inlining can reduce the overhead of function calls, especially for small, frequently called functions, leading to faster execution.

Are there any downsides to using inlining?

Yes, excessive inlining can increase the size of the binary and may lead to code bloat, which can negatively impact performance.

How do I declare a function as inline?

You can declare a function as inline by using the inline keyword before the function definition.

Can I inline member functions in classes?
