When should I use inline functions?

What are inline functions and when should I use them?

Inline functions are functions defined within a class or a method that can be expanded in place. You should use them when you want to improve performance by reducing function call overhead, especially for small, frequently called functions.

Are there any downsides to using inline functions?

Yes, while inline functions can improve performance, they can also increase the size of the binary if used excessively, leading to code bloat.

Can you give me an example of an inline function?

Sure! In C++, you can define an inline function like this: inline int add(int a, int b) { return a + b; }.

When should I avoid using inline functions?

Avoid using inline functions for large functions or when the function's logic is complex, as it may negate the performance benefits.
