Question

write a program of c++ that will loop through a 2D array of size 2*3 , and prints it out in a block of number.

Answer 1

Below is the solution:

#include<iostream>
using namespace std;
int main()
{
   // an array with 2 rows and 3 columns.
   int n[2][3] = {{0,1,2}, {2,3,4}}; //(2X3) array

   // output each array element's value
   for (int i = 0; i < 2; i++)
   {
       for (int j = 0; j < 3; j++)
       {
           //print each array element
           cout << "Element at n[" << i << "][" << j << "]: ";
           cout << n[i][j]<<endl;
       }
   }

   return 0;
}

sample output:

Element at n[0][0]: 0
Element at n[0][1]: 1
Element at n[0][2]: 2
Element at n[1][0]: 2
Element at n[1][1]: 3
Element at n[1][2]: 4
