program should print

1

2 1

3 3 1

4 6 4 1

and then should ask for input from user and then it should print the sum of the elements in that row

if we enter 1

then it should return 1

if we enter 2

then it should return 2+1 i.e. 3

for 3

3+3+1 i.e. 9..

This is Pascal's triangle.
using System;
using System.Collections.Generic;
using System.Text;

namespace PascalTriangle
{

   class PascalTriangle
   {
      static void Main(string[] args)
      {

         System.Console.WriteLine("Pascal Triangle Program");
         System.Console.Write("Enter the number of rows: ");
         string input = System.Console.ReadLine();

         int n = Convert.ToInt32(input);


         for (int y = 0; y < n; y++)
         {
            int c = 1;
            for (int q = 0; q < n - y; q++)
            {
               System.Console.Write("   ");
            }

            for (int x = 0; x <= y; x++)
            {
               System.Console.Write("   {0:D} ", c);
               c = c * (y - x) / (x + 1);
            }
            System.Console.WriteLine();
            System.Console.WriteLine();
         }
         System.Console.WriteLine();
      }
   }
}
