In this chapter, you got to know interesting new features introduced in C++17. You learned the super simple C++17 nested namespace syntax. You also learned datatype detection with a braced initializer list and the new rule imposed in the C++17 standard.
You also noticed that static_assert can be done without assert failure messages. Also, using std::invoke(), you can now invoke global functions, function pointers, member functions, and static class member functions. And, using structured binding, you could now initialize multiple variables with a return value.
You also learned that the if and switch statements can have a local-scoped variable right before the if condition and switch statements. You learned about auto type detection of class templates. Lastly, you used inline variables.
There are many more C++17 features, but this chapter attempts to cover the most useful features that might be required for most of the developers. Â In the next chapter, you will be learning about the Standard Template Library.
