Exercises

1. Create a simple class with an overloaded operator++. Try calling this operator in both pre- and postfix form and see what kind of compiler warning you get.
2. Create a class that contains a single private char. Overload the iostream operators << and >> (as in Iosop.cpp) and test them. You can test them with fstreams, strstreams, and stdiostreams ( cin and cout).
3. Write a Number class with overloaded operators for +, –, *, / , and assignment. Choose the return values for these functions so that expressions can be chained together, and for efficiency. Write an automatic type conversion operator int( ) .
4. Combine the classes in Unary.cpp and Binary.cpp.
5. Fix Fanout.cpp by creating an explicit function to call to perform the type conversion, instead of one of the automatic conversion operators.
