# MultiDimensional Array

When you are displaying the number of indexes you refer to the non existing element. E.g. 'array1[9]', has 9 elements, so the last element should have index [8].

That's how you can print all of the elements on screen. It's for 3x3 array, but obviously if you change array size, you must change loop condition too. int array[3][3]; for(int i = 0; i < 3; i++) { for(int j = 0; j < 3; j++) { cin >> array[i][j]; cout << array[i][j]; } } In this example the last element of an array is [2][2]. The first element always has index 0.

This is Solution : Don't forget to Upvote ................................................... using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Text; using System.Threading.Tasks; namespace SoloLearn { class Program { static void Main(string[] args) { int[,] num = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; //your code goes here for(int i=0; i<3;i++) { for(int j=0;j<3;j++) { Console.WriteLine(num[i,j]); } } } } }

Ok. I want to know, how lements multidimensional arrays can be print on screen? Please guide and help
