if - else statement

An if statement identifies which statement to run based on the value of a Boolean (true or false) condition.

The following are some common comparators that can be used when you set up conditions:

if(a == b) : if a is equal to b;
if(a < b) : if a is less than b;
if(a > b) : if a is greater than b;
if(a != b) : if a is not equal to b;

Type the following code :

using System;

namespace LearnCSharp
{
    class Program
    {
        static void Main(string[] args)
        {
            string result = string.Empty;
            int number = 5;

            if (number == 12)
            {
                result = "dozen";
            }
            else
            {
                result = "not a dozen";
            }

            Console.WriteLine($"The amount {number} is {result}");
        }
    }
}

Run the application in the Console Window

Output in Console Window

The amount 5 is not a dozen
