#include<iostream>

int main(){char a,c;int b;cin>>b;while(cin>>a){c=a+b;if(c>'z')c-=26;cout<<c;}}

@Huyuhao0215 c-=26写成x%=26

n可能很大

by GoodLuckCat @ 2023-08-18 10:30:19

应该是c%=26吧

AC了（不要Ctrl+c哦）

#include<bits/stdc++.h>
using namespace std;

int main()
{
    int n;
    cin>>n;
    string a;
    cin>>a;
    for(int i=0;i<a.size();i++){

        if(a[i]+n<='z')
        {
            a[i]+=n;
        }
        else
        {
            a[i]=a[i]+n-26;
        } 
    }
    cout<<a; 
    return 0;
}
