#include <vector>
using namespace std;

int main()
{
	int iarray[]={1,2,3,4,5};
	vector<int> ivector(iarray,iarray+sizeof(iarray)/sizeof(int));

	//元素的累计
	cout<<accumulate(ivector.begin(),ivector.end(),0)<<endl;
	//向量的内积
	cout<<inner_product(ivector.begin(),ivector.end(),ivector.begin(),10)<<endl;
	//向量容器中元素局部求和
	partial_sum(ivector.begin(),ivector.end(),ostream_iterator<int>(cout," "));
	cout<<endl;
	//向量容器中相邻元素的差值
	adjacent_difference(ivector.begin(),ivector.end(),
ostream_iterator<int>(cout," "));
	cout<<endl;
