而自由存储是C++中通过new和delete动态分配和释放对象的抽象概念,通过new来申请的内存区域可称为自由存储区。基本上,所有的C++编译器默认使用堆来实现自由存储,也即是缺省的全局运算符new和delete也许会按照malloc和free的方式来被实现,这时藉由new运算符分配的对象,说它在堆上也对,说它在自由存储区上也正确。 4. ...
规则:共158条,具备完整的描述和要求,无需额外的信息就可以对源代码进行合规性判定。 这些准则涵盖了标准C环境、未使用代码处理、数据类型和表达式、控制流、函数等多个方面,旨在最大限度地消除或减少编程错误。 1.4 重要性与作用 MISRA C:2012的重要性在于它提供了一个统一的、可遵循的C语言编程标准,有助于减少...
