Flow Control

After this first introduction to C#, we'll examine flow control and control structures. We'll need this information to implement code that is executed only under certain circumstances.

If/Else

Conditional execution is a core component of every programming language. Just like C and C++, C# supports If statements. To see how If statements work, we've implemented a trivial example:

using System;

class   Hello
{
        public static void Main()
        {
                int     number = 22;
                if      (number > 20)
                        Console.WriteLine("if branch ...");
                else
                {
                        Console.WriteLine("else branch ...");

                }
        }
}

Inside the C# program, we define an integer value. After that the system checks whether the value is higher than 20. If the condition is true, the code inside the If block is executed. ...
