cppcheck是一个轻量的跨平台的C C++ 代码静态检查工具，使用也很简单，这里备份下它的使用方法：

官网地址：

【 http://cppcheck.sourceforge.net/ 】

下载链接如下图，可以下载windows安装包，cppcheck源码，以及eclipse插件：

cppcheck的下载和安装在windows上是非常简单的，直接【 next 】即可。

cppcheck的使用：

界面语言的设置：

可在【编辑 - 首选项 - 语言】里选择

保存输出文件：

可在【文件 - 保存结果到文件】里选择

直接检查文件或目录：

可在【检查 - 文件/目录】里选择

检查结束后如下图：

cppcheck的输出文件结果实例：

cppcheck有4种输出结果：

输出XML1：
