-cout << fixed << setprecision(2) << setw(15) << left << result << "End of line" <<endl; using setw we can force the display of a certain number of characters. In this case, if the variable is more than 15 characters, it will be truncated, if not then white spaces will be added. The next (optional) setting (in this case "left" determines the orientation of the text.
