Agenda: C++: A One-Day Overview (2024-11-19 - 2024-11-21)

The “New C++”: Fundamental Changes Since 2011

Livehacking screenplay

• A Live-Hacked Tour Around The New C++

A live-coded overview of what will follow, showing the cornerstones of the “new C++”. Starting with a C++98 code base, we morph that into something that has a more modern appeal.

• Memory management/pointer types (std::shared_ptr<>, std::unique_ptr<>)

• Pythonicity: auto, Structured Binding, and more

• Lambdas

• Threading: threads, and locking

• Container classes and iteration: range based for

• Real container initialization

• Generalized typesafe unions: std::variant<>

• Generalized function pointer: std::function<>

• New OO features: final, overide

Low Hanging Fruit

Much of it has been said in the intro section, but let’s quickly repeat …

• Duck Typing (Err, auto) Without A Duck

• Tuple Unpacking (Err, Structured Binding)

• Range Based for Loops: Introduction

• Brace Initialization (Uniform Initialization)

• New-Style Union: std::variant

• std::function

Memory Management

• Introduction

• std::unique_ptr (and a little moving)

• std::shared_ptr

• std::weak_ptr (optional)

Lambdas

• Lambda

• Lambda: More Capturing

Multithreading

From Multithreading:

• Threads in C++

• std::mutex And Friends

• Scoped Locking

• std::atomic

Optional (But Cool) Topics

From Move Semantics, Rvalue References:

• Lvalues, Rvalues, And Moving

• Implementing Move Semantics (class String, Live Hacked)

• Using Move Semantics In Own Code

• Afterword, Further Reading

From Multithreading: communication primitives

• std::promise and std::future (And Some std::chrono) (Some Live Hacking)

• std::condition_variable (Live Hacking Multithreaded Queue)
