What are the performance implications of overloading in C++?

What are the performance implications of overloading in C++?

Overloading in C++ can lead to performance improvements by allowing function calls to be resolved at compile time, reducing runtime overhead.

Are there any downsides to using overloading?

Yes, excessive overloading can lead to code complexity and ambiguity, making it harder for the compiler to resolve which function to call.

How does overloading affect memory usage?

Overloading itself doesn't significantly affect memory usage, but it can lead to larger binaries if many overloads are defined.

Can you give an example of function overloading?

Sure! For instance, you can have a function add(int a, int b) and another add(double a, double b) to handle both integer and double addition.

Is there a performance difference between overloading and using templates?

Yes, templates can provide better performance in some cases since they are resolved at compile time, similar to overloading, but with more flexibility.
