纯享版：

#include <stdio.h>
int a, ans;
char c; 
signed main() {
	scanf("%lld ", &a);
	c = getchar();
	if(a < 1001)
		ans = 8;
	else
		ans = 8 + ((a - 1000) / 500 + 1) * 4;
	if(c == 'y')
		ans += 5;
	printf("%lld\n", ans); 
	return 0;
}

史上最简AC代码：

#include<bits/stdc++.h>
using namespace std;
int main(){ int g,yuan=8; char fu; cin>>g>>fu; if(g<=1000&&fu=='y'){cout<<13; return 0;} if(g<=1000&&fu=='n'){cout<<8; return 0;} g-=1000; while(g>0){yuan+=4; g-=500;} if(fu=='y') cout<<yuan+5; else cout<<yuan; return 0;}

看不懂的话看下面：

#include<bits/stdc++.h>
using namespace std;

int main(){
    int g,yuan=8;
    char fu;
    cin>>g>>fu;
    if(g<=1000&&fu=='y'){cout<<13; return 0;}
    if(g<=1000&&fu=='n'){cout<<8; return 0;}
    g-=1000;
    while(g>0){yuan+=4; g-=500;}
    if(fu=='y') cout<<yuan+5;
    else cout<<yuan;
    return 0;
}
