You can format output using <iomanip.h>, it's a standard header file.  Specifically you can use the setw(x) function.

int data = 50, data2 = 5;

cout << setw(3) << data << setw(3) << data2 << endl;

You use setw(x) like the endl operator.  It sets aside a "column" x spaces wide, and places everything to the far right of that column.  If the output needs more spaces than the column provides (e.g. data = 5000) then it will flood over and mess it up.
