@BreakPlus 这样吗？可是结果还是全错。

#include <cstdio>
#include <string.h>
#include <iostream>
#include <algorithm>
#include <math.h>
#include <vector>
using namespace std;

int main()
{
    int n;
    cin>>n;
    getchar();
    char s;
    while(1){
        s=getchar();
        if(s == '\r' || s == '\n'){
            break;
        }
        s=(s-'a'+n)%26+'a';
        putchar(s);
    }   

    return 0;
}
