Summary
In this chapter, you have learned how to use modern C++ features that will be used throughout this book. Automatic type deduction, move semantics, and lambda expressions are fundamental techniques that every C++ programmer needs to feel comfortable with today.
We also spent some time looking at error handling and how to think about bugs, along with valid states and how to recover from runtime errors. Error handling is an extremely important part of programming that is easily overlooked. Thinking about contracts between callers and callees is a way to make your code correct and avoid unnecessary defensive checks in the released version of your program.
In the next chapter, we will look into strategies for analyzing and measuring performance in C++.
