Overview of C++

  • C++ is multiparadigm, systems programming language.
  • The main purpose is to be a high-level language, without
    • sacrificing any performance
  • This means that in C++ you don't pay for features that you don't
    • use.

Multiparadigm

  • Structured
  • Object Oriented
  • Functional
  • Data Oriented

And multithreaded

And compile-time

C++ renaissance?

Free lunch

  • Processors are getting faster and faster

The Free lunch is over

An article by Herb Sutter in 2005

Sequential execution is reaching the physical limits.

Viva la multicore revolution

  • Processors have multiple cores
  • Every single core executes multiple instructions simultaniously

Here comes the electricity bill

Processors are hitting new barriers

  • power consumption
  • heat generation

Mobile

  • Processors are slower
  • Power is pretty limited
  • Users are in a hurry

Portability

C and C++ are one of the most portable languages

  • there are compilers for every platform
  • the 3 most popular compilers cover all desktop platforms, iOS, Android, PlayStation 4, XBox

Brief history of C++

1979 - Bjarne Stroustrup started developing "C with Classes" in Bell Labs

1983 - C++ is born. cfront works by translating C++ to C and compiling
