c++中字符串反转的3种方法

#include <iostream>
#include <string>
#include <algorithm>
using namespace std;

int main()
{
string s = "hello";

reverse(s.begin(),s.end());

cout<<s<<endl;

return 0;
}

#include <iostream>
using namespace std;

void Reverse(char *s,int n){
for(int i=0,j=n-1;i<j;i++,j--){
char c=s[i];
s[i]=s[j];
s[j]=c;
}
}

int main()
{
char s[]="hello";

Reverse(s,5);

cout<<s<<endl;

return 0;
}

#include <iostream>
#include <cstring>
using namespace std;

int main()
{
char s[]="hello";

strrev(s);

cout<<s<<endl;

return 0;
}
