About C++

#include "hello_world.h"

namespace hello_world {

std::string hello()
{
    return "Hello, World!";
}

}

C++ (pronounced cee plus plus) is a general purpose programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. It is immensely popular, particularly for applications that require speed and/or access to some low-level features. It is considered to be an intermediate level language, as it encapsulates both high and low level language features.

C++ supports procedural, object-oriented, functional and generic programming. Compilers for C++ are available for essentially every platform, including Windows, Mac OS, and Linux.

Key Benefits:

  • Type safety: Encapsulate necessary unsafe operations
  • Resource safety: Not all resource management is managing memory
  • Performance: For some parts of almost all systems, it's important
  • Predictability: For hard and soft real-time systems
  • Teachability: Complexity of code should be proportional to the complexity of the task
  • Readability: People and machines ("analyzability")
  • Direct map to hardware: of instructions and fundamental data types
  • Zero-overhead abstraction: Classes with constructors and destructors, inheritance, generic programming, functional programming techniques

The standard for C++ is maintained by the International Organization for Standardization (ISO), and the current version of C++ as of June 2018 is C++17 (named not as the 17th version of C++, but rather signifying that the standard was ratified in 2017).

The best thing about C++ is that it runs on everything from embedded processors with very limited resources to the largest mainframe supercomputer and every personal computer in between.

Exercism is a great website

The reviews are incredibly helpful because they help me see things that I missed, learn about new ways and sometimes interesting discussions that can add a fun twist to maybe a simple problem.

Relaxed. Encouraging. Supportive.

C++ is a powerful language, and I love it for its speed and abundance of utilities. It works both at high-level and low-level, simple and complex program.

Professional C++ dev who loves learning and mentoring, currently pursuing a masters in Data Analytics. Also, a student here on the Rust and R tracks (at least).

I worked with C++ during my first job as a developer 4 years ago and continued to use it in my scientific thesis. I love the power of this language and want to further refine my mastery over its various uses.
Fun. Challenging. Interesting
