The C++ programming language has been changed dramatically since its invention in 1979. Some people in this era might be a little bit scared to code using C++ language since it is not user-friendly. The memory management we have to deal with sometimes makes people unwilling to use this language. Fortunately, since C++11--also known as modern C++, along with C++14 and C++17--has been released, numerous features have been introduced to simplify our code in the C++ language. Moreover, the best part of it is that the C++ programming language is a great language for any project, from low-level programming to web programming, as well as functional programming.
This chapter is the best place to start our journey in this book, as it is addressed to the C++ programmers to refresh their knowledge and will discuss the following topics:
- Understanding several new features in modern C++
- Implementing the C++ Standard Libraries in modern C++
- The use of the Lambda expression and all features included in C++ Lambda
- Using smart pointer to avoid manual memory management
- Dealing with many return values using tuples
