C++

C++ is a high-level, general-purpose programming language created by Danish computer scientist Bjarne Stroustrup. First released in 1985 as an extension of the C programming language, it has since expanded significantly over time; as of 1997 C++ has object-oriented, generic, and functional features, in addition to facilities for low-level memory manipulation. It is almost always implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Embarcadero, Oracle, and IBM.

See C++ on Wikipedia.

Getting started

Here is a Hello, World! program file in C++, hello-world.cpp:

#include<iostream>

using namespace std;

int main() {
  cout << "Hello, World!";

  return 0;
}

To compile a C++ program, use clang++:

clang++ hello-world.cpp -o hello-world

To run a compiled C++ program, run:

./hello-world
