What are the disadvantages of using macros in C++?

What are the disadvantages of using macros in C++?

Macros can lead to code that is hard to read and debug, as they don't follow the same scoping rules as functions.

Can you give me an example of how macros can cause issues?

Sure! For instance, if a macro is defined with a name that conflicts with a variable, it can lead to unexpected behavior.

Are there alternatives to using macros?

Yes, you can use inline functions or constants instead, which provide type safety and better debugging.

What about performance? Do macros affect performance?

Macros are expanded at compile time, so they can improve performance in some cases, but they can also bloat the code.

Is there a specific scenario where macros are particularly harmful?

Yes, in large codebases, macros can create maintenance challenges and obscure errors, making debugging difficult.
