LEARNING OBJECTIVES
- Identify deprecated and removed C++17 language/library features and update code to modern equivalents
- Apply C++17 evaluation-order rules and copy-elision guarantees to write safer, more predictable code
- Implement template solutions using CTAD, deduction guides, fold expressions, and if constexpr
- Use structured bindings, init statements, inline variables, and improved lambdas to simplify code
- Apply C++17 standard attributes (nodiscard, fallthrough, maybe_unused, deprecated) to improve diagnostics
- Use optional, variant, any, and string_view safely, including lifetime, access, and performance tradeoffs
- Build a CSV processing tool using filesystem, from_chars, string_view, and parallel STL algorithms

ABOUT THIS COURSE
C++ started in 1979 as an experiment, before being officially launched in 1983. In 1998, its first ISO standard was released. What started as an experimental language has quickly turned into a platform for solving complex problems that drive many industries: gaming, finance, data centres, vehicles, and even software for space missions, among many others. The latest release, C++17, builds upon the functionality of previous versions by further diversifying the power of C++ and increasing the language's readability.
This course describes all the significant changes in C++17 and will give you the essential knowledge to stay at the edge of the latest features. What’s more, each section contains lots of practical examples and uses a bottom-up approach to give you a more comfortable start. If you have a moderate understanding of C++, this course is highly recommended as the next step in mastering the modern form of this language.
