If you jump to step 3 you’ve missed the point. The best way to use any advice/resource/information/opinions on software best practices (including this one!) is to follow these three steps, in strict order: I asked the question around the Embedded FM water cooler and got a lot of good answers, so I’ll summarize them here.Ĭlean coding, design, code reviews, revision control, style: these all fall under the umbrella of “software best practices.” These 10 rules can be a good reference for C developers who are looking for a minimal set of rules to follow but will positively impact the robustness of their code base.A friend and former colleague emailed me this question: “I’m going to be leading a group of firmware engineers and I’m looking for resources about clean coding, design, code reviews, revision control, coding style, etc. They were formulated to provide a concise but strict set of rules that aims to improve software reliability and testability. The Power of 10: Rules for Developing Safety Critical CodeĬreated by an engineer at the NASA Jet Propulsion Laboratory in 2006, these 10 rules were created for C programs running mission-critical applications. It focuses on providing rules to improve the protection of software applications against security vulnerabilities. This is a coding standard from the CERT (Computer Emergency Response Team) for the SEI (Software Engineering Institute). While it has ‘Motor’ in the title it is also used for several security and safety critical systems such as railway, aerospace, telecommunications and medical. MISRA comes as a standard for C and C++ and is a widely adopted standard for Embedded systems applications. MISRA stands for Motor Industry Software Reliability Association. We’ll list coding standards for 11 programming languages, 10 of these featured in the top 10 ranked programming languages according to the PYPL index. It’s not a complete reference list and of course, there are tons more coding standards for each language! This article will list some popular coding standards that are useful for software practitioners to follow when writing code for a particular programming language. To put it simply, coding standards any set of documented rules and guidelines that recommend coding practice and styles that when followed should lead to improved code quality. They can be documented rules set by a development team, industry level rules and regulations on code written for critical level applications or coding guidelines written by individuals to ensure consistency in their programming style.Īll these together form coding standards developers use to increase the efficiency and performance of the program and to even reduce technical debt. The source of coding standards can vary and exist in many forms. For languages with similar syntax and rules, some standards can also be used interchangeably between such languages.Īdvantages of following coding standards includes code with improved readability, security, maintainability, safety and robustness. Most programming languages have coding standards assembled to provide rules and guidelines on using best practices for that particular language. Coding standards provide guidelines on how to write code with the intention of following best practices and ultimately improving software quality.
