c++中字符串的反转

#include <iostream>
#include <cstring>
using namespace std;
int main()
{
    char s[]="123456";//不能是string类型；
    strrev(s);
    cout<<s<<endl;
    return 0;
}

#include<iostream>
#include <cstring>
#include <algorithm>
using namespace std;
int main()
{
    string s[]="123456";
    reverse(s.begin(),s.end());
    cout<<s<<endl;
    return 0;
}
