#include <string.h>
int main()
{
    char c[100];
    gets(c);
    int len=strlen(c);
    for(int i=len-1;i>=0;i--)
    {
        printf("%c",c[i]);
    }
    return 0;
}

gets在c++里被弃用了 应该用string+getline

#include <bits/stdc++.h>//万能头文件，包含所有c++&c头文件（罢
using namespace std;
string c;//
int main()
{
    getline(cin,c);//
    int len=c.length();//
    for(int i=len-1;i>=0;i--)
    {
        printf("%c",c[i]);
    }
    return 0;
}

@Tim0509 错误的.

char 数组可以用 scanf("%s",); 读入.
