Question

I have the following program that generates a multiplication table. A formatting problem arises when the outputs reach the double digits. How do I straighten out the columns?

#include <iostream>

using namespace std ;
int main() 
{
  while (1 != 2)
  {
    int column, row, c, r, co, ro; 

    cout << endl ;

    cout << "Enter the number of columns: " ;
    cin >> column ;
    cout << endl ;
    cout << "Enter the number of rows:    " ;
    cin >> row ;
    cout << endl ;

    int temp[column] ;
    c = 1 ; 
    r = 1 ; 
    for(ro = 1; ro < row ; ro ++ ){
      for(co = 1; co < column ; co ++ ){
            c = c ++ ;
            r = r ++ ;
            temp [c]= co * ro;

            cout << temp[c] << " ";
      }
      cout << endl ;
    }
    system("pause");  
  }
}

Answer 1

use the setw output manipulator:

cout << setw(3) << temp[c];

By default, this uses spaces to fill, which it looks like you want.

You will need to include iomanip as the documentation says.
