學弟可以先用陣列存好再做喔

給個示範

#include<bits/stdc++.h>
using namespace std;
int main()
{
    string s;
    cin>>s;
    int y[26]={10,11,12,13,14,15,16,17,34,18,19,20,21,22,35,23,24,25,26,27,28,29,32,30,31,33};
    int sum=0;
    for(int i=0; i<s.length(); i++)
    {
    	if(i==0) sum+=y[int(char(s[0]))-65]/10+(y[int(char(s[0]))-65]%10)*9;
    	else  sum+=(9-i)*(s[i]-'0');
	}
	sum+=s[9]-'0';
	if(sum%10==0) cout<<"real"<<endl;
	else cout<<"fake"<<endl;
