What are the situations for overloading functions in C++?

Function overloading refers to the situation where functions have the same name but different parameter lists within the same scope. There are several different cases of function overloading in C++.

1. The number of parameters is different.
2. Different types of parameters.
3. The order of the parameters is different.
4. const and non-const parameters
5. Generic type parameter
6. Pointer type parameter

By combining the above situations, function overloading can be achieved. It is important to note that the return type of a function does not affect function overloading, only the parameter list does.
