C++11 and C++14 New Features

C++11 and C++14 New Features

Audience

Designers and developers who are using, considering using, or wish to know about the expanded capabilities of C++11 and C++14 will find this course useful.

Prerequisites

Attendees should be experienced with C++ and comfortable with its primary features (e.g., classes, templates, inheritance, STL, etc.). Familiarity with threading concepts (e.g., threads and mutexes) is helpful, but is not essential.

Duration

2 days.

Course Objectives

Thought you knew C++? Think again! The C++11 standard is a huge leap forward in the language and STL. Largely inspired by Boost, the C++11 standard introduces 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.

Topics:

  • 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
