Source Code

The source code examples–starting with the details part–shown in the course are complete. That means, assuming you have a conforming compiler, you can compile and run them. I put the name of the source file in the title of each source code example. The source code uses four whitespaces for indentation. Only for layout reasons, I sometimes use two whitespaces.

Furthermore, I’m not a fan of namespace directives such as using namespace std as they make the code more difficult to read and can pollute namespaces. Consequently, I use them only when it improves the code’s readability (e.g.: using namespaces std::chrono_literals). When necessary for layout reasons, I apply a using-declaration such as using std::chrono::system_clock. To summarize, I only use the following layout rules if necessary:

• I indent two characters instead of four.
• I apply the using namespace std directive.
