好东西,绝对是好东西,我向大家推荐

#include <iostream.h>
int main()
{
	float n,a,b,c;
	cin>>n;
	while(n!=0)
	{
		cin>>a>>b>>c;
		if(((a-b)<0.001)&&((a-b)>-0.001)&&((c-b)<0.001)&&((c-b)>-0.001)&&((a-c)<0.001)&&((a-c)>-0.001)) {cout<<"1"<<endl;}
			else if((a==b)||(a==c)||(b==c))
			{
				if((((a*a+b*b-c*c)<0.001)&&((a*a+b*b-c*c)>-0.001))||(((a*a-b*b+c*c)<0.001)&&((a*a-b*b+c*c)>-0.001))||(((-a*a+b*b+c*c)<0.001)&&((-a*a+b*b+c*c)>-0.001))) {cout<<"2"<<endl;}
					else {cout<<"3"<<endl;}
			}
			else if((((a*a+b*b-c*c)<0.001)&&((a*a+b*b-c*c)>-0.001))||(((a*a-b*b+c*c)<0.001)&&((a*a-b*b+c*c)>-0.001))||(((-a*a+b*b+c*c)<0.001)&&((-a*a+b*b+c*c)>-0.001))) {cout<<"4"<<endl;}
				else if((a+b<=c)||(a+c<=b)||(c+b<=a)) {cout<<"6"<<endl;}
					else {cout<<"5"<<endl;}
		n--;
	
	}
}
