The text output of a program should be well-formatted for readability as well as displaying
numbers with the proper notation and precision levels. The default output formatting in C++ is
often not desirable, so one can add explicit instructions to the cout stream. These manipulators
and functions are defined in the library.
• setw (n): set the width (number of characters) of the next item to be at least n.
• If the next item width is less than n, then pad the item with extra spaces.
• If the next item width is greater than n, then the entire next item is output.
• left and right: when used in conjunction with setw (); justify the item to one side
forcing the padding to the other side. Note that these manipulators are persistent, i.e. remains
effective until the next change occurs.
• fixed: use the fixed-point notation (the decimal point notation that we are familiar with)
when displaying a numerical item. Note that fixed defaults to 6 decimal points if the data
type is float or…
