Learn OOP with C#

C# an Introduction.

It is one of the languages which evolved from C programming like C++ with object-oriented development. It has a feature named 'Garbage Collection' which makes beginners understand them easily and quickly. This allows C# to stand different from C and C++.

Some of its features are:

• Object-Oriented
• Comes with an extensive class library
• Supports exception handling.
• Multiple types of polymorphism
• Separation of interfaces from implementations.

Mostly, C# is used to develop desktop apps and games. It has powerful development tools, multi platform support and generics makes C# a good choice.

C# is used for:

• Rapid application development projects.
• Projects implemented by small or large teams.
• Internet/Web applications.
• Projects with strict reliability requirements.

C# is case-sensitive. That means name and Name are not the same variables here.

Sample Hello World Program in C#:

//Declaration of namespace

Using System;

//Beginning of the start class

Class HelloWorld

{

    //Main program begins here

    Static void Main()

    {

       //writing to console

       console.Writeline("Hello World!");

    }

}

Output =>  Hello World!

From the above example, you can understand that a program here has consist of 4 basic parts namely,

1. namespace declaration
2. a class
3. main method
4. program statement 

Recommended IDE to use is : Visual Studio .
