Getting Output

I try to simplify this as much as possible. You can write 1000, 10000 or even 50000 lines of code. How will you check whatever code you've written is correct? You need to Run(Compile) the code and if system is doing whatever you expected than whatever code you've written is correct.

During this entire walkthrough we going to use a user friendly medium called Console for getting output and also for giving input. (There are lot of other mediums also like MessageBox, Notepad file, Excel file etc, since console is easily understandable we going to use this for now. In Upcoming articles we going to study something called File handling where we'll study how to use files to communication to system). Watch the below code section and write your First code.

NOTE
Read C# introduction part and follow the steps to install and open visual studio code editor. once you open Visual studio code editor, you will find lot of pre defined keywords like using system, class, static, void, main, string[], args etc. No need to worry about all those things for now. We going to study each and every keyword in detail in upcoming articles. But for now as a Begineer what you need to keep in mind is whatever code you going to type, type it inside { and } which present after static void Main(string[] args)

CODE

static void Main(string[] args) {
    Console.WriteLine("Hello World!");
}

Code Explanation
If you compile the above code by pressing ctrl+F5(Windows) or cmd+F5(MAC), you will see a black window , that black window is nothing but console(Our medium), inside that you will see Hello World! text printed out. So above in code iam telling the system to write Hello World text in the console
