The objected oriented programming: application to potential well system

The Objected Oriented Programming is a new methodology which allows us to organize the code in a different way than the structured languages. This article describes the main characteristics of the Language C++, and advantages in physics computing and in building a graphic user interface. The solution of a classical exercise in one-dimensional Quantum Mechanics: to find out the energy levels and the wave functions of a potential well system, allows us to set a class hierarchy, use the concepts of overloading and polymorphism, and read or write data to disk through the input/output streams.
