What are the best practices for using macros in C++11?

In C++11, it's recommended to use inline functions or constexpr instead of macros for type safety and better debugging.

Why should I prefer inline functions over macros?

Inline functions provide type checking and scope, which macros do not. This helps prevent errors and improves code readability.

Can you give an example of a macro that could be replaced with an inline function?

Sure! Instead of using a macro like #define SQUARE(x) ((x) * (x)), you can use an inline function: inline int square(int x) { return x * x; }.

Are there any situations where using macros is still appropriate?

Yes, macros can be useful for conditional compilation or defining constants, but they should be used sparingly.
