Hi, thanks in advance for your help. I rememer doing this with a different programming language, but forgot how. Can someone tell me how I can make the output of the following array so all the rows and columns line up like a matrix (or a box if you prefer)? Thanks again.

int main()

{
      int arr[3][5]=
      {
            {1,2,3,4,5},
            {6,7,8,9,10},
            {11,12,13,14,15}
      };


      for (int i=0;i<3;i++)
      {
            cout << "[";
            for (int j=0;j<5;j++)
                  cout << arr[i][j]<< " ";
                  cout << "]" << endl;
      }

getch();
}

try changing

 cout << arr[i][j]<< " ";

to


 cout << arr[i][j]<< "\t";

i.e replace the space after the element by a 'tab' , is this the result what you wanted ?

You can use setw() formatting function:

#include <iostream>
#include <string>
#include <iomanip>

using namespace std;

int main()
{
     int arr[3][5]=
     {
          {1,2,3,4,5},
          {6,7,8,9,10},
          {11,12,13,14,15}
     };


     for (int i=0;i<3;i++)
     {
          cout << "[";
          for (int j=0;j<5;j++)
               cout << setw(4) << arr[i][j]<< " ";
               cout << "]" << endl;
     }

     getch();
}
