CppCheck是一个C/C++代码缺陷静态检查工具。不同于C/C++编译器及其它分析工具，CppCheck只检查编译器检查不出来的bug，不检查语法错误。所谓静态代码检查就是使用一个工具检查我们写的代码是否安全和健壮，是否有隐藏的问题。(CppCheck is a C/C++ code defect static checking tool. Unlike the C/C++ compiler and other analysis tools, CppCheck checks only the bug that the compiler does not check, and does not check the syntax errors. The so-called static code check is to use a tool to check whether the code we write is safe and robust, and whether there is a hidden problem.)
