Thread: setw and while statements

Hey, I am doing a while statement where I am manipulating the outputs. My problem is I dont know how to manipulate each ouput.
eg: int 1 = 0;

while(i < 10 )

{
i = 1 + 2;
cout << '\n' <<setw(3);
cout<< '\n' <<setw(5);

I want to display each output of "i"(2,4,6,8,10), using setw to manipulate the spacing and I dont know how. Thanx for your help.


Tony.

What do you want the spacing to be? How are you trying to display your output? My best guess is that you want to display the output in a diagonal.

Code:

// don't forget this for setw()
#include <iomanip.h>  // or <iomanip> if using namespace

int main()
{
    int i = 0;

    while ( i < 10 )
    {
        i+=2;
        cout << setw(i - 2) << i << endl;
    }

    return 0;
}

/*Output

2
  4
    6
      8
        10
*/
