All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible. Check the return value of all non-void functions, or cast to void to indicate the return value is useless.
A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
Consistent coding standards can, in turn, make the measurements more consistent. Special tags within source code comments are often used to process documentation, two notable examples are javadoc and doxygen. The tools specify the use of a set of tags, but their use within a project is determined by convention.
The Joint Strike Fighter project C++ Coding Standards [3] are based on MISRA-C:1998. The NASA Jet Propulsion Laboratory C Coding Standards [ 4 ] are based on MISRA-C:2004. IEC 81001-5-1:2021 Health software and health IT systems safety, effectiveness and security - Part 5-1: Security - Activities in the product lifecycle cites MISRA C as an ...
Many organizations and open-source projects adopt specific coding standards to facilitate collaboration and reduce cognitive load. Style guidelines can be formalized in documents known as coding conventions, which dictate specific formatting and naming rules. These conventions may be prescribed by official standards for a programming language ...
To reduce the effort needed to read and understand source code; [1] To enable code reviews to focus on issues more important than syntax and naming standards. To enable code quality review tools to focus their reporting mainly on significant issues other than syntax and style preferences.
Example 2: legacy code may have been compiled and tested on 32-bit architectures, but when compiled on 64-bit architectures, new arithmetic problems may occur (e.g., invalid signedness tests, invalid type casts, etc.). Example 3: legacy code may have been targeted for offline machines, but becomes vulnerable once network connectivity is added ...
The coding standard may be a standard conventions specified by the language vendor (e.g. The Code Conventions for the Java Programming Language, recommended by Sun), or custom defined by the development team. Extreme Programming backers advocate code that is self-documenting to the furthest degree possible.
