Arrays and Strings
Data has to live somewhere, and arrays and strings are the most fundamental containers. In this chapter we first revisit the underlying mechanics of C-style arrays—getting clear on why they are so "bare"—then jump straight to std::array and get a taste of just how sweet zero-overhead abstraction is. The string part follows the same arc, moving from C-style strings to std::string, where you will find that working with text in modern C++ feels a generation ahead of C.
