V.resize (2*v.size) orV.resize (2*v.size, 99) doubles the capacity of V (and initializes the value of the new element to 99)3., v.empty () to determine whether the vector is empty4. vn returns the element n in the V5. v.insert ( 9、pointer, number, content) inserts the ...

容器:各种数据结构,如vector、list、deque、set、map等,用来存放数据,从实现角度来看,STL容器是一种class template。算法:各种常用的算法,如sort、find、copy、for_each。从实现的角度来看,STL算法是一种function tempalte.迭代器:扮演了容器与算法之间的胶合剂,共有五种类型,从实现角度来看,迭代器是一种将operator...
因此删除vector中任意位置上元素时,vs就认为该位置迭代器失效了注意:Linux下,g++编译器对迭代器失效的检测并不是非常严格,处理也没有vs下极端从上述三个例子中可以看到:SGI STL中,...,vector的容量为: " << v.capacity() << endl; // 经过上述reserve...
