@Mrlvbo 你应该判断字符加 n 后是否大于 z 然后在进行操作

@Mrlvbo 附代码 O v O

#include<bits/stdc++.h>
using namespace std;
int n;
string s; 
int main()
{
    cin>>n>>s;
    int len=s.length();
    for(int i=0;i<len;i++)
    {
        if(s[i]+n<='z')
        {
            s[i]+=n;
        }
        else
        {
            s[i]+=(n-26)%26;
        }
    }
    cout<<s<<endl;
    return 0;
}
