代码：

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

int a, b, c, d, e;
int main() {
	cin >> a >> b >> c >> d >> e;
	int sum = a + b + c + d + e;
	if(sum >= 0 && sum <= 99) {
		cout << "Gray";
		return 0;
	}
	else if(sum >= 100 && sum <= 119) {
		cout << "Blue";
		return 0;
	}
	else if(sum >= 120 && sum <= 169) {
		cout << "Green";
		return 0;
	}
	else if(sum >= 170 && sum <= 229) {
		cout << "Orange";
		return 0;
	}
	else if(sum <= 230 && sum <= 500) {
		cout << "Red";
		return 0; 
	} 
}

为什么啊！！！
