C++20 Algorithms Playbook
If the C++ Standard Library seems intimidating, try getting started with it through the <algorithms> header. This course will teach you how to find pre-written functions that will speed up your development.
What you'll learn
The C++ Standard Library is large and powerful. Many C++ developers avoid it, and write things by hand instead. That’s slower and harder work. In this course, C++20 Algorithms Playbook, you’ll learn to use the functions in to get your work done quickly and safely. First, you'll discover simple examples where using an algorithm is more expressive and easier than writing a loop yourself. Next, you'll explore searching and sorting a collection, transforming elements of a collection, and copying part of one collection to another. Finally, you'll see how to combine algorithms to complete complex tasks without writing complex code. When you’re finished with this course, you’ll have the skills and knowledge of the standard header needed to write clearer and better code with less effort and time spent.
