Question

write a program to find row sum and column sum of a matrix?

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(); } }
