每加一判断一次 比z大了就换成a

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int n;
    cin>>n;
    n%=26;
    char ch;
    while(cin>>ch) cout<<((ch+n)>'z'?(char)(ch+n-26):(char)(ch+n));
    return 0;
} 

判断简单一点吧不用挨着加

加了个判断，得了80分，什么鬼操作第4个点WA

#include<iostream>
#include<string>
using namespace std;
int main() 
{
    int a;
    string b;
    cin>>a;
    cin>>b;
    if(a%26==0)
   {
    cout<<b;return 0;
   }
    for(int i=0;i<b.size();i++)
    {
        int c;
        c=(int)b[i]-96;
        c+=a;
        if((int)c%26==0)    
        {
            c=1;    
        }
        else {c%=26;}
        c+=96;
        cout<<(char)c;
    }
    return 0;
}
