Note: If you are new to C# and Console Application. Try to code First C# Program

Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code these pattern.

Practical Implementation:

using System;

namespace patternProblem
{
    class Pattern121
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Enter loop iteration times: ");
            int n = Convert.ToInt32(Console.ReadLine());
            int j;
            int i;
            Console.WriteLine("-----Output-----");
            Console.WriteLine();

            for (i = 1; i <= n; i++)
            {
                for (j = n; j >= i; j--)
                {
                    Console.Write(" ");
                }
                for (j = 1; j <= i; j++)
                {
                    Console.Write("*");
                }
                for (j = j - 1; j >= 1; j--)
                {
                    Console.Write("*");
                }
                Console.WriteLine();
            }
            for (i = n; i >= 1; i--)
            {
                for (j = n; j >= i; j--)
                {
                    Console.Write(" ");
                }
                for (j = 1; j <= i; j++)
                {
                    Console.Write("*");
                }
                for (j = j - 1; j >= 1; j--)
                {
                    Console.Write("*");
                }
                Console.WriteLine();
            }

            Console.ReadKey();
        }
    }
}

Output:
The input number here is 5. So, the program will iterate five times. The output is shown below:

Enter loop iteration times:
5
-----Output-----
