用switch case 做的，莫名其妙50分

#include<bits/stdc++.h>
using namespace std;
string n;
int a,b,c,d,e,f,g,h,i;
int ans;
int sum;
int zb(int ans){
	if (ans<9) return ans;
	if (ans=88) return ans;
}
int main(){
	getline(cin,n);
	for (int j=0;j<=n.size();j++){
		switch(j){
			case 0:a=n[j]-'0';break;
			case 2:b=n[j]-'0';break;
			case 3:c=n[j]-'0';break;
			case 4:d=n[j]-'0';break;
			case 6:e=n[j]-'0';break;
			case 7:f=n[j]-'0';break;
			case 8:g=n[j]-'0';break;
			case 9:h=n[j]-'0';break;
			case 10:i=n[j]-'0';break;
			case 12:{
				ans=n[j];
				if (ans<88) ans = ans-'0';
				else ans = ans-0;
				break;
			}
		}
	}
	sum = a*1+b*2+c*3+d*4+e*5+f*6+g*7+h*8+i*9;
	sum%=11;
	sum = zb(sum);
	if (sum==ans) printf("%s","Right");
	else{
		ans = sum;
		for (int j=0;j<=n.size();j++){
			switch(j){
				case 0:printf("%d",0);break;
				case 1:printf("%c",'-');break;
				case 2:printf("%d",b);break;
				case 3:printf("%d",c);break;
				case 4:printf("%d",d);break;
				case 5:printf("%c",'-');break;
				case 6:printf("%d",e);break;
				case 7:printf("%d",f);break;
				case 8:printf("%d",g);break;
				case 9:printf("%d",h);break;
				case 10:printf("%d",i);break;
				case 11:printf("%c",'-');break;
				case 12:{
					if (ans<9) printf("%d",ans);
					else printf("%c",ans); 
					break;
				}
				}
			} 
		}
	return 0;
}

求更改
