所以用reserve(size_type)只是扩大capacity值,这些内存空间可能还是“野”的,如果此时使用“[ ]”来访问,则可能会越界。而resize(size_type new_size)会真正使容器具有new_size个对象。 在对vector进行访问时,如果使用“[ ]”,则会像变通数组那样,不进行越界的判断。如果使用“at(size_type)”函数则会先进行越界...

because more memory is allocated to handle future growth. This way a vector does not need to reallocate each time an element is inserted, but only when the additional memory is exhausted. The total amount of allocated memory can be queried usingcapacity()function. Extra memory can be returned...
