setw
•setw (set width) lets us control how many character positions the next
data item should
occupy when it is output. (used for numbers and strings, not chars).
•The argument to setw is an integer fieldwidth specification, the
data item is right-justified within the fieldwidth.
•If you don’t specify enough characters, the minimum number of characters
is used anyway.
