KaloVale,

I have made a simple example for ya in order to give you the brief idea about  setw() and how does it work.
Compile this program and run in ur machine :

[code]
int main()
{
  int sales [3][5]={ {1,2,3,4,5},
  {6,7,8,9,10},
  {100,101,102,103,104}};


  cout<<"                Item #0 Item #1 Item #2  Item #3 Item #4  Totals"<<endl;


  //create rows/columns of text representing arrays
  for (int salesperson = 0 ; salesperson <3 ; salesperson++)
  {
    cout <<"Salesperson"<<setw( 2 ) <<salesperson;
    int sum =0;

    for (int item =0; item <5 ; item++)
    {
      cout << setw( 8 )<< sales[salesperson][item];
      sum+=sales[salesperson][item];
    }
    cout<<setw( 8 ) <<sum <<endl;
  }
  cout <<endl;
  cout <<"Totals"<<setw( 14 ); // 14 spaces

  for (int j = 0;j<5;j++)
  {
    int sum = 0;

    for (int i =0; i<3; i++)
    {
      sum+= sales[i][j];
    }
    cout<<sum<<setw( 8 ); // 8 spaces
  }
  cout<<endl;
}[/code]

Hope it helps :)
