Abstract:

This paper presents some of the basic principles of object oriented programming (OOP), using one of the common programming language, C sharp - C#. OOP is nowadays usually used programming paradigm, so it should be used to give students different project assignments. Elementary difference between procedural and object oriented paradigm will be discussed. Comparison between C#, C++ and Java programming languages will be also briefly noted. Afterwards, Windows application using C# will be briefly explained, by programming a simple calculator with basic mathematical functions (add, subtract, multiply, divide), as well as basic trigonometric functions (sine, cosine, power, exponential, factorial, etc). Limitations that pose current standard variables regarding its size will be briefly discussed. Finally, it will be explained that, by using different already implemented forms and classes in C# language, students can learn basics about OOP, but also about mathematical principles that can make their application run faster.
