reverse,reverse_copy,rotate,rotate_copy

代码直接贴了

//reverse  reverse_copy
#include<iostream>
#include<string>
#include<vector>
#include<algorithm>
#include<functional>
using namespace std;
int main(){
	int a[]={1,2,3,4,5,6,7,8,9,10};
	vector<int>v(a,a+10);
	reverse(v.begin(),v.end());
	copy(v.begin(),v.end(),ostream_iterator<int>(cout," "));
	cout<<endl;

	reverse(v.begin()+1,v.end()-1);
	for(vector<int>::iterator itera=v.begin();itera!=v.end();++itera){
		cout<<*itera<<" ";
	}
	cout<<endl;

	reverse_copy(v.begin(),v.end(),ostream_iterator<int>(cout," "));
	cout<<endl;
	system("pause");
	return 0;
}

//rotate rotate_copy
#include<iostream>
#include<string>
#include<algorithm>
#include<functional>
#include<vector>
using namespace std;

	vector<int>v(a,a+10);
	vector<int>vv(a,a+10);
	rotate(v.begin(),v.begin()+3,v.end());//相当于循环移动类似于valarray的cshift(+) cshift(-);advance(+),advance(-)
	for(vector<int>::iterator iter=v.begin();iter!=v.end();++iter){
		cout<<*iter<<" ";
	}
	cout<<endl;
	rotate(v.begin(),find(v.begin(),v.end(),7),v.end());

	advance(pos,1);
	rotate_copy(vv.begin(),pos,vv.end(),ostream_iterator<int>(cout," "));
	cout<<endl;
	pos=vv.end();           //若没有这句，则会报错，从v.begin()+  从v.end()-
	advance(pos,-2);
	rotate_copy(vv.begin(),pos,vv.end(),ostream_iterator<int>(cout," "));
	cout<<endl;
	system("pause");
