#include <iostream>
#include <cstring>
#include <cmath>
#include <algorithm>
#include <iomanip>
using namespace std;
int main()
{
    string a;
    cin >> a;
    for(int i = a.size();i >= 0;i--)
    {
        cout << a[i];
    }
    return 0;

不用了，改了一下

#include <iostream>
#include <cstring>
#include <cmath>
#include <algorithm>
#include <iomanip>
using namespace std;
int main()
{
    string a;
    cin >> a;
    for(int i = a.size() - 1;i >= 0;i--)
    {
        cout << a[i];
    }
    return 0;
}

@MuYuMC 一个万能头，5行变一行：

#include <bits/stdc++.h>
