C++ Crash Course: a fast-Paced Introduction

Chapter 14: Iterators
This is the interface between the containers 
you learned about in the previous chapter and the strings of the next 
chapter. You’ll learn about the different kinds of iterators and how their 
design provides you with incredible flexibility.
Chapter 15: Strings
This chapter teaches you how to handle human 
language data in a single family of containers. You’ll also learn about 
the special facilities built into strings that allow you to perform com-
mon tasks.

Chapter 16: Streams
You’ll be introduced here to the major concept 
underpinning input and output operations. You’ll learn how to handle 
input and output streams with formatted and unformatted operations, 
as well as how to employ manipulators. You’ll also learn how to read 
and write data from and to files.
Chapter 17: Filesystems
Here you’ll get an overview of the facilities 
in the stdlib for manipulating filesystems. You’ll learn how to construct 
and manipulate paths, inspect files and directories, and enumerate 
directory structures. 
Chapter 18: Algorithms
This is a quick reference to the dozens of 
problems you can solve easily from within the stdlib. You’ll learn about 
the impressive scope of the high-quality algorithms available to you. 
Chapter 19: Concurrency and Parallelism
This chapter teaches you 
some simple methods for multithreaded programming that are part 
of the stdlib. You’ll learn about futures, mutexes, condition variables, 
and atomics.
Chapter 20: Network Programming with Boost Asio
Here you’ll 
learn how to build high-performance programs that communicate 
over networks. You’ll see how to use Boost Asio with blocking and 
non-blocking input and output.
