When should I use function overloading in C++?

Can you explain when to use function overloading in C++?

Function overloading in C++ allows you to define multiple functions with the same name but different parameters. It's useful when you want to perform similar operations with different types or numbers of inputs.

What are some examples of function overloading?

For instance, you might have a function add(int a, int b) for adding integers and another add(double a, double b) for adding floating-point numbers. Both can be called add, but they handle different types.

Are there any downsides to using function overloading?

Yes, overloading can lead to ambiguity if the compiler cannot determine which function to call based on the arguments provided. It can also make code harder to read if overused.

How does function overloading differ from function overriding?

Function overloading is about having multiple functions with the same name but different parameters in the same scope, while function overriding involves redefining a base class function in a derived class with the same signature.
