Summary
In this chapter, you learned how to use the basic concepts in the Algorithm library, the advantages of using them as building blocks instead of handwritten for-loops, and why using the standard Algorithm library is beneficial for optimizing your code at a later stage. We also discussed the guarantees and trade-offs of the standard algorithms, meaning that you can, from now on, use them with confidence.
By using the advantages of the algorithms instead of manual for-loops, your code base is well prepared for the parallelization techniques that will be discussed in the coming chapters of this book. One key feature that the standard algorithms are missing is the possibility to compose algorithms, something that was highlighted when we tried to avoid unnecessary container copies. In the next chapter, you will learn how to use views from the C++ Ranges library to overcome this limitation of standard algorithms.
