#include <iostream>
#include <cstring>
using namespace std;
string str;
int len;
int main()
{

    cin >> str;
    len = str.length();
    for (int i = len; i >= 0; i--)
    {
        cout << str[i];
    }

}

很简单的一道题

#include<iostream>
#include<string.h>
using namespace std;
int main(){
    char n[100];
    cin >> n;
    int len=strlen(n);

    for(int i=len-1;i>=0;i--){
        cout << n[i];
    }
    return 0;
}
