Putting multiple statements on a single line lowers the code readability and makes debugging the code more complex. foo(); bar(); // Noncompliant Write one statement per line to improve readability. foo(); bar(
It allows for catching coding errors at compile time and it documents the code for maintainers. Correctly const-qualifying pointers can be tricky because the indirection they add can also be const. For a pointer X * ptr, const can be written in three different places: const X * ptr and ...
Static code analysis tools for C Utilize static code analysis to find issues in C such as bugs, code smells & security vulnerabilities. Use the Sonar language analyzer with hundreds of rules to evaluate your code and ensure the security, reliability and maintainability of your software. ...

静态分析(static analysis)是指在不执行代码的情况下对其进行分析评估的过程,是软件质量和软件安全保障的重要一环。它通过词法分析、语义分析、控制流分析、数据流分析等技术对代码逐行解析暴露问题,从而协助我们将许多在运行时才会暴露的棘手麻烦扼杀于摇篮之中。

Cppcheck ——A tool for static C/C++ code analysis Cppcheck是 C/C++ 代码的静态分析工具。它提供独特的代码分析来检测错误,并专注于检测未定义的行为和危险的编码结构,目标是减少误报。 Cppcheck可以集成到众多流行的开发工具当中,比如: Jenkins-Cppcheck 插件...
用途:存放未初始化或初始化为0的全局/静态变量(如 int y; 或 static int z = 0;)。 特点: 不占用ELF文件的实际空间(仅记录长度),加载时由操作系统分配并清零内存。 提升存储效率(无需在文件中存储大量零值)。 .rodata 段(Read-Only Data) 用途:存放只读数据(如字符串常量、const全局变量等)。
