这里

if(a[ans]=='z'){
    a[ans]='a'+n-1;

应该是

if(a[ans]=='z'- n){
    a[ans]='a'+n-1;

@LSR120218_juruo AC code:

#include <iostream>
using namespace std;

int main() {
    int n,ans=0;
    char a[53];
    cin >>n;
    cin>>a;
    while(a[ans]!='\0'){
        if(a[ans]+n>'z'){
            a[ans]= (a[ans] + n) - 26;
        }else{
            a[ans]+=n;
        }
        ans++;
    }
    cout<<a;

    return 0;
}
