Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

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


Apart from the stream-based input/output library, the standard library provides a series of helper functions, called manipulators, that control the input or 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, and will continue showing more manipulators in the next recipes. 

Getting ready

The I/O manipulators are available in the std namespace in 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 textual representation of Booleans:
        std::cout << std::boolalpha << true << std::endl;    // true
