Programming in C++11/14

Course objectives

Delegates will learn:

• new features introduced to the language and standard library in the C++11/14 standard
• language extensions such as nullptr, auto and decltype deduction mechanisms, range-based for loop, strongly typed enums (scoped enums), and uniform initialization syntax
• implementation of move semantics for classes
• perfect forwarding mechanism
• practical use of lambda expressions in combination with the STL library
• new features in the Standard Library, such as std::tuple, hashing containers, and new standard algorithms

Course syllabus

C++98 vs. C++11 and C++14

Core language features

• New basic types
• Raw strings
• nullptr keyword
• Type deduction in modern C++
  • auto
  • decltype
• Functions and trailing return type
• Scoped enumerations
• Range-based-for loops
• Uniform initialization syntax
• Initializers list
• Type aliases, alias templates

New features in C++ classes

• Defaulting special member functions - default
• Default initialization of non-static members
• Delegating and inheriting of constructors
• Overriding virtual methods - override
• Blocking inheritance and overriding using final

Move semantics

• Motivation for move semantics
• l-values and r-values
• rvalue references
• Implementing move semantics for user types
  • Move constructors
  • Move assignment operators
• Using std::move() function
• Perfect Forwarding
• noexcept keyword

Lambda expressions

• Lambda expressions
  • Closure classes and objects
  • Capturing local variables – closures
• Lambdas in C++14 – generic lambdas
• Passing lambdas to functions
• Storing lambdas in variables

Templates in C++11

• Static assertions - static_assert
• Type Traits in Standard Library
• Variadic templates

Compile-time programming in C++11/14

• Running code at compile time
  • constexpr expressions
  • constexpr functions

Novelties in Standard Library

• Smart pointers - std::unique_ptr, std::shared_ptr and std::weak_ptr
• New features in STL containers (move semantics, new member functions, etc.)
• std::array – convenient wrapper for native arrays
• Hash containers
• Tuples – std::tuple
• std::function – callbacks in C++11/14
• New STL algorithms

Writing asynchronous code in C++11/14

• Asynchronous functions – std::async() and std::future
