Overview of this book

C++ is one of the most widely used programming languages and is applied in a variety of domains, right from gaming to graphical user interface (GUI) programming and even operating systems. If you're looking to expand your career opportunities, mastering the advanced features of C++ is key. The book begins with advanced C++ concepts by helping you decipher the sophisticated C++ type system and understand how various stages of compilation convert source code to object code. You'll then learn how to recognize the tools that need to be used in order to control the flow of execution, capture data, and pass data around. By creating small models, you'll even discover how to use advanced lambdas and captures and express common API design patterns in C++. As you cover later chapters, you'll explore ways to optimize your code by learning about memory alignment, cache access, and the time a program takes to run. The concluding chapter will help you to maximize performance by understanding modern CPU branch prediction and how to make your code cache-friendly. By the end of this book, you'll have developed programming skills that will set you apart from other C++ programmers.

6. Streams and I/O

Introduction

In the previous chapter, we covered one of the most challenging topics – concurrency in C++. We looked at the main multithreaded concepts and differentiated between synchronous, asynchronous, and threaded execution in C++. We learned the key points about synchronization, data hazards, and race conditions. Finally, we looked at working with threads in modern C++. In this chapter, we will go deeper and learn how to handle I/O in multithreaded applications.

This chapter is dedicated to streams and I/O in C++. I/O is the general concept of input and output operations. The main purpose of this part of the Standard Library is to provide a clear interface regarding the input and output of data. But this is not the only goal. There are a lot of situations where I/O can help us in our applications. It's hard to imagine any application that doesn't write errors or exceptional situations into the log file with the purpose of sending it to the development team for analysis...
