这是代码

include <iostream>```

include <cstring>

using namespace std; int main(){ int n; cin>>n; char j[n]; cin>>j; char w[n]; for(int i=0;i<strlen(w);i++){ if(j[i]!='z'){ w[i]=j[i]+n; }else{ w[i]='a'; }

 }
 cout<<w;

}

?

include <iostream>``` include <cstring> using namespace std; int main(){ int n; cin>>n; char j[n]; cin>>j; char w[n]; for(int i=0;i<strlen(w);i++){ if(j[i]!='z'){ w[i]=j[i]+n; }else{ w[i]='a'; }

} cout<<w; }

sss

include <iostream>``` include <cstring> using namespace std; int main(){ int n; cin>>n; char j[n]; cin>>j; char w[n]; for(int i=0;i<strlen(w);i++){ if(j[i]!='z'){ w[i]=j[i]+n; }else{ w[i]='a'; }

} cout<<w; }```

#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
int main(){
    string s;
    int n;
    cin>>n>>s;
    for(int i=0;i<=s.size()-1;i++){
        if(s[i]+n>'z'){
            s[i]=char(int((s[i]+n-'a')%26))+'a';
            continue;
        }
        s[i]+=n;
    }
    cout<<s;
    return 0;
}

AC代码

问题较多，自己比对吧！！！不客气！
