Part 4. Part 4. Solving Specific Problems

The last part of the book groups functions and macros dedicated to the solution of specific programming problems. Examples of such broad category are concurrency, polymorphic types, definition of variables, formatting and printing and many others.

This part of the book uses a less formal structure to describe functions and abandons the fixed template adopted in the previous parts. In doing so, the book wants to focus even more on practical aspects of everyday programming. For this reason, functions in the following sections are more likely to appear grouped by area of application.

The last chapter titled "the toolbox", takes this approach to the extreme giving just a brief summary of all the remaining namespaces in the standard library. This choice also reflects the fact that some functions have a very narrow field of application.
