hey guys, how to align the integers in right order in visual c++.
I have a matrix to print out with right alignment.I can print out the matrix but the integer values donot align in the right order.
for example | 1  10  -8|
                   | 12 2  3   |
this is what my code does, which is straight forward 
 but the result should be   | 1  10  -8|
                                      |12    2    3| which is more prettier
I know setw() fuction. But I am not able to get it right. Am I not using setw() correctly?

Ok the example comes out to be horribly wrong here!! the idea is to right align the integer value.

hey raxi thanks for the reply, but I think quick google shows gotoxy() is not visual c++ library fuction.
and  I am not trying to move whole matrix around the screen.I just want to align/adjust (right adjust)  the digits of top row and subsequent bottom rows of the matrix in right order. for example if you have 1 on top row and 10 at the bottom row. Normal output is that the 1 of the top row would be on top of the 1 of the bottom row. What I want is aligning that 1 of the top row so that it remains on top of 0 not 1.

Have been out of touch with C++ from long time , but try something like below.
int
main () {
cout <<setw (10);
cout <<right<< 77 << endl;
return 0;
}

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 :)

TechGuy and LahureDai I appreciate it!! And TechGuy that was exactly what I was looking for!! it works.    
LahureDai that works great when u make a output in one line, but if you have to output  multiple line with a' for loop' than data may not align in required order. but techGuy gave what I needed.
Thanks again guys!!
