Using I/O manipulators to control the output of a stream

Apart from the stream-based I/O library, the standard library provides a series of helper functions, called manipulators, that control the input and output streams using operator<< and operator>>. In this recipe, we will look at some of these manipulators and demonstrate their use through some examples that format the output to the console. We will continue covering more manipulators in the upcoming recipes.

Getting ready

The I/O manipulators are available in the std namespace in the headers <ios>, <istream>, <ostream>, and <iomanip>. In this recipe, we will only discuss some of the manipulators from <ios> and <iomanip>.

How to do it...

The following manipulators can be used to control the output or input of a stream:

• boolalpha and noboolalpha enable and disable the textual representation of Booleans:

  std::cout << std::boolalpha <&lt...
