我一开始设成50就wa，设成200就ac了
#include<iostream>
#include<math.h>
#define MAX 200
using namespace std;
struct color
{
	int red;
	int blue;
	int green;
};
int main()
{
	int r,b,g;
	color c[MAX];
	for(int i=0;i<16;i++)
	{
		cin>>c[i].red>>c[i].blue>>c[i].green;
	}
	while(cin>>r>>b>>g)
	{
		if(r==-1&&b==-1&&g==-1)
			break;
		int min=1<<20;
		int flag=0;
		for(int i=0;i<20;i++)
		{
			int length = sqrt(pow((r-c[i].red)*1.0,2)+pow((b-c[i].blue)*1.0,2)+pow((g-c[i].green)*1.0,2));
			if(length<min)
			{
				min = length;
				flag = i;
			}
		}
		cout<<"("<<r<<","<<b<<","<<g<<") maps to ("<<c[flag].red<<","<<c[flag].blue<<","<<c[flag].green<<")"<<endl;
		

	}
	return 0;

}

• why?c只存了16个值 (790) kevinCoder 2010-11-26 17:58:34
