Every \u00a0project has its own style guide: a set of conventions about how to write code for that project.\u00a0<\/span>Some managers choose a basic coding rules, others prefer very advanced ones and for many projects no coding rules are specified, and each developer uses his style.<\/p>\n

The coding style has a big impact on\u00a0the source code readability, investing some hours to train developers, and doing periodically a code review is always good to make the code easy to maintain and evolve.<\/span><\/p>\n

Many resources exist talking about the better coding rules to adopt. However \u00a0even if\u00a0thousands of practices\u00a0are recommended, \u00a0the developers focus only on some of them.<\/p>\n

In case of C++ here’s the list of the 10 most voted best practices in our C++ best practices repository:<\/a><\/p>\n

1- Always compile at the highest warning level possible<\/a>:\u00a0A lot of bugs can be avoided by paying attention to compiler diagnostics<\/span><\/p>\n

2-\u00a0Code that is not used (commented out) shall be deleted<\/a><\/p>\n

3-If you can exit a function early, you should<\/a>:\u00a0Early exits out of a function, specially through guard clauses at the top of a function are preferred since they simplify the logic further down in the function.<\/span><\/p>\n

4-\u00a0Avoid methods with too many local variables<\/a>:\u00a0Methods where NbVariables > 8 are hard to understand and maintain.\u00a0<\/span>Methods where NbVariables > 15 are extremely complex and must be refactored<\/span><\/p>\n

5-\u00a0Avoid types with too many fields<\/a>:\u00a0Types where fields count > 20 \u00a0\u00a0might be hard to understand and maintain but there might be cases where it is relevant to have a high number of fields.<\/span><\/p>\n

6-\u00a0Avoid types with too many methods<\/a>:\u00a0Types where methods count > 20 might be hard to \u00a0understand and maintain but there might be cases where it is relevant to have a high number of methods.<\/span><\/p>\n

7- Avoid too big\u00a0types<\/a><\/p>\n

8- Avoid too complex methods<\/a><\/p>\n

9-\u00a0Avoid methods with too many parameters<\/a><\/p>\n

10-\u00a0Avoid too big methods<\/a><\/p>\n

As we can remark the most voted rules\u00a0are the most basic and generic ones, every developer could just use the common sens to respect them, and these rules may be applied to any other language.<\/p>\n","protected":false},"excerpt":{"rendered":"
