Getting closer with several new features in modern C++

So, what is new in modern C++ in comparison to the old one? There are so many changes in modern C++ compared to the old one, and the book pages will dramatically increase if we discuss all of them. However, we will discuss the new features in modern C++, which we should know about, to make us more productive in coding activities. We will discuss several new keywords, such as auto, decltype, and nullptr. We will also discuss the enhancement of the begin() and end() function that has now become a non-member class function. We will also discuss the augmented support for the for-each technique to iterate over collections using the range-based for loop techniques.

The next few subsections in this chapter will also discuss the new features of modern C++, namely Lambda expressions, smart pointers, and tuples, which were just added in the C++11 release.
