c.reserve() 保留适当的容量。 c.size() 返回容器中实际数据的个数。 c1.swap(c2) swap(c1,c2) 将c1和c2元素互换。 同上操作。 vector<Elem> c vector <Elem> c1(c2) vector <Elem> c(n) vector <Elem> c(n, elem) vector <Elem> c(beg,end) c.~ vector <Elem>() 创建一个空的vector。

The second constructor is a default copy constructor that can be used to create a new vector that is a copy of the given vectorc. 翻译:第二个构造器是一个默认的复制构造函数,它可以用来创建一个新的向量,它是给定向量c的副本。 The third constructor creates a vector with space fornumobjects. If...

指定位置插入,要注意的是这里不再像string一样,用的size_t 的pos,vector虽然也可以用下标访问,但是为了承接后面STL其他不支持下标访问的容器,所以这边的pos用的是迭代器类型 指定位置删除 交换两个容器的指针,其实只是交换了空间,跟全局的swap区别就是全局的swap还涉及到了开空间和拷贝 ...
