Programming in C++17

Course objectives

Delegates will learn:

• new elements of the C++ language and standard library introduced in the C++17 standard
• structured bindings for tuples, structs, and user types (tuple protocol)
• control flow statements with an initialization section
• use of constexpr if in generic code
• new features in C++ templates, such as parameter deduction for template classes (CTAD) and fold expressions
• new types available in the Standard Library std::string_view, std::optional, std::any, and std::variant
• concurrent algorithms - Parallel STL
