Demonstrates
The sample consists of two classes, EURO, representing Euros, and USD, representing U.S. Dollars. Form1 acts as a test application for the two classes. Users can enter various values for USD, execute the operators, and convert USD to EURO.
The following programming techniques are demonstrated:
Overloaded operators. The USD class has these overloaded operators: constructor, +, -, *, /.
Narrowing and Widening operators. Both the EURO and USD classes have widening and narrowing conversion to and from Double.
