that the notion of a “deep copy” depends on the type `T` of elements in the vector: if `T` performs a deep copy, then so does the `std::vector`, but if `T` performs a shallow copy, then semantically `std::vector` also performs a shallow copy.' id: totrans-307 prefs: []...
1.模板类vector-->是一种动态数组-->可以在运行时设置长度-->它是使用new创建动态数组的替代品。 vector类自动通过new和delete来管理内存。 vector<typeName> vt(n_elm);typeName:类型,vt:对象名,n_elm:个数:整型常量/变量 2.模板类array(C++11)-->与数组一样,array对象长度也是固定的,也使用栈(静态内存...
