@qiangzian 循环里第一个判断改一下就行了

#include<bits/stdc++.h>
using namespace std;
int n,a,l;
string s;
int main()
{
    cin>>n;
    cin>>s;
    l=s.size() ;
    for(int i=0;i<l;i++)
    {
        if(s[i]+n>122)
            s[i]=s[i]+n-26;
        else
            s[i]+=n;
        cout<<s[i];
    }
    return 0;
}
