Try this though you'll need to add some error checking to make the program robust: using System; class Program { static void Main() { Console.Write("Enter number of rows of matrix (max 18) : "); int numRows = int.Parse(Console.ReadLine()); Console.Write("Enter number of columns of matrix (max 18) : "); int numCols = int.Parse(Console.ReadLine()); Console.WriteLine("Enter elements of the matrix (integers only)
"); // allow an extra row and column for the sums int[,] m = new int[numRows + 1, numCols + 1]; for(int i = 0; i { for(int j = 0; j { Console.Write(" Row {0}, Col {1} : ", i + 1, j + 1); m[i, j] = int.Parse(Console.ReadLine()); m[i, numCols] += m[i, j]; m[numRows, j] += m[i, j]; m[numRows, numCols] += m[i, j]; } } // display results Console.WriteLine(); Console.Write("R/C "); for(int i = 0; i Console.WriteLine(" Sum"); Console.WriteLine(new string ('-', 4 * numCols + 8)); for (int i = 0; i { if (i if (i == numRows) { Console.WriteLine(new string ('-', 4 * numCols + 8)); Console.Write("Sum "); } for(int j = 0; j { Console.Write(" {0, 2} ", m[i, j]); } Console.WriteLine(); } Console.ReadKey(); } }
