我弄了一个队列，queue<string> temp，v6就warning．
改成char*就没有，并且过了，怎么回师啊
#include <iostream>
#include <queue>
#include <string>
#include <iomanip>
using namespace std;
int main()
{
	double per;
	double tempa,tempr;
	string tempu,tempv;
	queue<string> temp;	
	while (1)
	{
		cin >> tempa;
		if(tempa<0)
		{break;}
		cin>>tempu;
		cin>> tempr;
		cin>>tempv;
		per = (100 * (tempa / tempr));
		if ( per >= 1 )
		{
			cout << fixed<<setprecision(1)<<tempv;
		cout <<' '<<tempa<<' '<<tempu<<' ';
		cout <<per<<'%'<<endl;
		}
		else 
		{}
	}
	cout <<"Provides no significant amount of: "<<endl;
	return 0;
}
