c++语言中std::rotate怎么用

1、基本语法格式：void rotate(ForwardIterator first, ForwardIterator middle, ForwardIterator last)该语法表示调换一个序列中子序列[first, middle)与[middle ,last）的位置。

3、vector类型的用法这种类型需要使用内置的迭代器来确定first,middle和last的位置。具体实例：#include<iostream>#inclu颊俄岿髭de<algorithm>using namespace std;int main(){ vector<int >v={1,2,3,4,5,6,7}; cout<<"old vector"<<" "; for (auto x : v) cout<<x<<" "; cout<<endl; rotate(v.begin(),v.begin()+2,v.end()); cout<<"New vector "; for (int i=0;i<v.size();i++) cout<<v[i]<<" "; cout<<endl；}

5、数盲褓梆尺组的用法：具体看实例#include<iostream>#include<algorithm>using namespace std;int main(){ int a[]={1,2,3,4,5,6,7}; cout<<"old array "; for (int i=0;i<7;i++) cout<<a[i]<<" "; cout<<endl; rotate(a,a+2,a+7); cout<<"NEW array "; for (int i=0;i<7;i++) cout<<a[i]<<" "; cout<<endl;}
