vector向量end()函数运用实例

end函数

语法:

1 2	iterator end(); const_iterator end() const;

end() 返回最末元素的迭代器(注:实指向最末元素的下一个位置)

源代码

/**

* Returns a read/write iterator that points one past the last

* element in the %vector. Iteration is done in ordinary

* element order.

iterator

end() { return iterator (this->_M_impl._M_finish); }

/**

* Returns a read-only (constant) iterator that points one past

* the last element in the %vector. Iteration is done in

* ordinary element order.

const_iterator

end() const { return const_iterator (this->_M_impl._M_finish); }

#include <iostream>

#include <vector>

using namespace std;

int main()

{

vector<int> v1(5, 0);

vector<int> v2(10, 2);

vector<int>::iterator iter = v1.begin();

for(iter;iter!=v1.end();iter++){

cout<<(*iter)<<endl;

}
