“Within C++ is a smaller, simpler, safer language struggling to get out.” – Bjarne Stroustrup
The C++ Core Guidelines are a collaborative effort led by Bjarne Stroustrup, much like the C++ language itself. They are the result of many person-years of discussion and design across a number of organizations. Their design encourages general applicability and broad adoption but they can be freely copied and modified to meet your organization’s needs.
The aim of the guidelines is to help people to use modern C++ effectively. By “modern C++” we mean C++11 and C++14 (and soon C++17). In other words, what would you like your code to look like in 5 years’ time, given that you can start now? In 10 years’ time?
For example if you want to set an explicit exit code. Calling python scripts will usually result in an exit code
0after the script is run. If you want to set a different exit code for example1to indicate some error occured you can do that viasys.exit(1).Same thing applies to other languages of course.
