C# Program to print Alphabet Triangle

In this C# program, we will take input (Number of rows) from the user and print the alphabet triangle based on the number of rows input by the user.

C# Program to print Alphabet Triangle Code:

 private static void Main(string[] args)
        {
            char ch = 'A';
            int i, j, k, m, n;
            Console.Write("Enter the number of rows:");
            n = int.Parse(Console.ReadLine());
            for (i = 1; i <= n; i++)
            {
                for (j = n; j >= i; j--)
                {
                    Console.Write(" ");
                }
                for (k = 1; k <= i; k++)
                {
                    Console.Write(ch++);
                }
                ch--;
                for (m = 1; m < i; m++)
                {
                    Console.Write(--ch);
                }
                Console.Write("\n");
                ch = 'A';
            }
            Console.ReadLine();
        }
