Restrictions on Overloaded Functions

Functions that differ only in return type cannot have the same name.
Two member functions that differ only in that one is declared with the keyword static cannot have the same name.
A typedef is a synonym for another type, not a separate type. The following two declarations of spadina() are declarations of the same function:
```
      typedef int I;
      void spadina(float, int);
      void spadina(float, I);
```
A member function of a derived class is not in the same scope as a member function in a base class with t he same name. A derived class member hides a base class member with the same name.
Argument types that differ only in that one is a pointer* and the other is an array[] are identical. The following two declarations are equivalent:
```
      f(char*);
      f(char[10]);
```
