A
aa
BBB
bbbb
CCCCC
cccc
DDD
dd

The program for the pattern is written in C# programming language and will accept a number as input. The loops will iterate based on the number of entry.

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 Pattern104
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Enter loop iteration times: ");
            int n = Convert.ToInt32(Console.ReadLine());
            int j;
            int i;
            int temp = 0;
            Console.WriteLine("-----Output-----");
            Console.WriteLine();


            for (i = 1; i <= n; i++)
            {
                if (i % 2 != 0)
                {
                    temp++;
                }
                for (j = 0; j < i; j++)
                {
                    if (i % 2 == 0)
                    {
                        Console.Write((char)(temp + 96));
                    }
                    else
                    {
                        Console.Write((char)(temp + 64));
                    }
                }

                Console.WriteLine();
            }

            if (i == (n + 1))
            {
                for (i = i - 2; i >= 1; i--)
                {
                    if (i % 2 != 0)
                    {
                        temp++;
                    }
                    for (j = 0; j < i; j++)
                    {
                        if (i % 2 == 0)
                        {
                            Console.Write((char)(temp + 96));
                        }
                        else
                        {
                            Console.Write((char)(temp + 64));
                        }
                    }                   

                    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
