Question

How to print a specific row of a matrix in C#

Answer 1

using System;
 
public class PrintSpecificRowOfMatrix_CSharp
{
    public static void PrintSpecificRowOfMatrix(int[][] matrix, int row) {
        int cols = matrix[0].Length;
        
        for (int j = 0; j < cols; j++) {
            Console.Write(matrix[row][j] + " ");
        }
    }
 
    public static void Main(string[] args)
    {
        int[][] matrix = new int[][]
        {
            new int[] {4, 7, 9, 18, 29, 0},
            new int[] {1, 9, 18, 99, 4, 3},
            new int[] {9, 17, 89, 2, 7, 5},
            new int[] {19, 49, 6, 1, 9, 8},
            new int[] {29, 4, 7, 9, 18, 6}
        };
 
        int row = 2;
 
        PrintSpecificRowOfMatrix(matrix, row);
    }
