How do you print a floating-point number with field width 10 and two digits
after the decimal point, using only the standard library?
C
printf("%10.2f", x);
C++
cout << setw(10) << setprecision(2) << showpoint << x;
Java
java.text.NumberFormat formatter
= java.text.NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
s = formatter.format(x);
for (int i = s.length(); i < 10; i++)
System.out.print(' ');
System.out.print(s);
