 So far we have encountered `noskipws` which is a *stream manipulator* that works on input streams. The exact details of how this, and other, manipulators work is unimportant for the purposes of using them, however in general they are put to the stream object with either `<<` or `>>`. *Stream flags* can also be explicitly set or cleared using the member functions `setf()` and `unsetf()`, and *stream parameters* can be set using named member functions such as `width()` and `precision()`.
 
-Getting formatted output to "look right" is quite tricky and relies to a great extent on trial-and-error combined with (tedious) manual checking of program's output. For some performance-critical code, using C++ streams and manipulators may not be practical or desirable. Also, providing localization (*l10n*) to the user's language and other settings can be difficult when using interleaved manipulators and messages. These caveats are a large part of the reason for C++20 adopting *libfmt* into the Standard Library (as `std::format` and associated types).

For some performance-critical code, using C++ streams and manipulators may not be practical or desirable. Also, providing localization (*l10n*) to the user's language and other settings can be difficult when using interleaved manipulators and messages. For these reasons, considering instead use of the `print()` and `format()` family is recommended.
 
 The following program produces a simulated cash-till receipt formatted to a width of 20 characters. This program is longer than most of the ones we've seen, and uses `struct` and `std::vector` introduced in previous Chapters. All of the text formatting functionality is in the `main()` program, so try and run the program and compare its output with the multiple uses of `cout` in the code (note that any product descriptions inputted may not contain spaces):
