Modern C++20 Development

Thought you knew C++? Think again! The C++11 standard saw a huge leap forward in the language and STL. Largely inspired by Boost, the C++11 standard introduced support for lambdas, multithreading, vastly improved object construction mechanisms, and much more beside. This course takes a deep and detailed look at all the new features on offer in C++11, along with the incremental additional changes in C++14, C++17, and C++20.

What you will learn:

• Working with C++11 smart pointers.
• Functional programming in C++11.
• Defining and using lambda expressions.
• Using C++11 container classes.
• Implementing code applications in C++11.
• Using miscellaneous C++ language features.
• What's new in C++ 14, C++17, and C++20.

Prerequisites:

• 3-6 months C++ programming experience

Course outline:

• General Language Enhancements in C++11: auto variables; Using auto in template definitions; Using decltype; New return syntax; Range-based for loops; Making your own classes iterable; Generalised constant expressions; Strongly-typed enums; Null pointers; Explicit overrides; Static asserts

 

• Additional Language Features in C++11: Lvalues, rvalues, and rrvalues; Movability; Reference binding rules; Support for movability in the STL; Improved initialization syntax; Inheriting and delegating constructors; Regular expressions; Date and time; Chrono; Explicit conversions; Variadic templates

 

• Miscellaneous New Language Features in C++14: Function return type deduction; Alternate type deduction in declarations; Relaxed constexpr restrictions; Variable templates; Aggregate member initialization; Standard user-defined literals
