10 用enum class替代enum enum成员属于enum所在的作用域,因此作用域不能出现同名实例 C++11引入了限定作用域的枚举类型。enum class enumclassX {a,b,c};inta=1;//可;但是enum就不可以Xx=X::a;//可Xy=b;//不可 enum class不会进行隐式转换 c++11以前enum class不允许前置声明 使用enum更方便的场景只有...

区别4,struct/class/enum/enum class, 在讲述之前,我先提醒一下大家在C++中, struct 和 class 对编译器看来,只有默认的成员变量作用域不同,一个是public,另一个是private,然后其他没有区别;推荐一个知乎不错的回答 c++为什么要让struct可以定义成员函数?,我引用一下里面的一些精华内容,从3点概括C++编译器可以做...
