Display Even Numbers from 10 to 20, Skipping 16, in 3 Different Ways Using C#

In this C# program, we will display the even numbers between 10 and 20, inclusive, but excluding the number 16. The program will demonstrate how to do this in three different ways using different looping structures. Specifically, the program will:

Use a loop that increments by 2 in each iteration (effectively only hitting even numbers), and will skip 16 using the continue statement.

Use a loop that increments by 1 in each iteration, but will also skip 16 using the continue statement.

Use an endless loop (while(true)), and will manage breaking the loop and skipping 16 with a combination of break and continue.

The program is designed to show the flexibility of control flow in loops and the use of continue and break to manage iterations and conditionally skip certain numbers.

Objective

Write a C# program to display the even numbers from 10 to 20, both inclusive, except for 16, in three different ways:

Incrementing 2 in each step (use continue to skip 16).

Incrementing 1 in each step (use continue to skip 16).

With an endless loop (using break and continue).

The challenge in this task is to implement the three methods using different loop strategies, while adhering to the constraints of skipping a specific number (16) in each case.

Example C# Exercise

 Copy C# Code 
using System;

namespace EvenNumbersExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Display even numbers from 10 to 20, skipping 16 - Method 1: Incrementing by 2
            Console.WriteLine("Method 1: Incrementing by 2 (Skipping 16)");
            for (int i = 10; i <= 20; i += 2)  // Increment by 2 to get only even numbers
            {
                if (i == 16) continue;  // Skip the number 16 using continue
                Console.Write(i + " ");
            }
            Console.WriteLine("\n");

            // Display even numbers from 10 to 20, skipping 16 - Method 2: Incrementing by 1
            Console.WriteLine("Method 2: Incrementing by 1 (Skipping 16)");
            for (int i = 10; i <= 20; i++)  // Increment by 1 to check all numbers from 10 to 20
            {
                if (i == 16) continue;  // Skip the number 16 using continue
                if (i % 2 == 0)  // Check if the number is even
                {
                    Console.Write(i + " ");
                }
            }
            Console.WriteLine("\n");

            // Display even numbers from 10 to 20, skipping 16 - Method 3: Endless loop with break and continue
            Console.WriteLine("Method 3: Endless loop with break and continue");
            int j = 10;
            while (true)  // Endless loop
            {
                if (j > 20) break;  // Exit the loop if the number exceeds 20
                if (j == 16)  // Skip the number 16
                {
                    j++;
                    continue;
                }
                if (j % 2 == 0)  // Check if the number is even
                {
                    Console.Write(j + " ");
                }
                j++;  // Increment the number for the next iteration
            }
            Console.WriteLine();
        }
    }
}

 Output

Method 1: Incrementing by 2 (Skipping 16)
10 12 14 18 20 

Method 2: Incrementing by 1 (Skipping 16)
10 12 14 18 20 

Method 3: Endless loop with break and continue
10 12 14 18 20
