#include<stdio.h>

    int main(void)

    {

        int t,q;

        float side1[30],side2[30],side3[30],maxmumside;

        scanf("%d",&t);

        for(q=0; q<t; q++)

        {

                 scanf("%f %f %f",&side1[q],&side2[q],&side3[q]);

                 }

        for(q=0; q<t; q++)

        {

                 if(side1[q]==side2[q]==side3[q]){printf("Case %d: Equilateral\n",q+1); continue;}

                 if(side1[q]>side2[q]&&side1[q]>side3[q]){maxmumside=side1[q]; if(side2[q]+side3[q]<maxmumside){printf("Case %d: Invalid\n",q+1);continue;}}

                 if(side2[q]>side1[q]&&side2[q]>side3[q]){maxmumside=side2[q]; if(side1[q]+side3[q]<maxmumside){printf("Case %d: Invalid\n",q+1);continue;}}

                 if(side3[q]>side2[q]&&side3[q]>side1[q]){maxmumside=side3[q]; if(side2[q]+side1[q]<maxmumside){printf("Case %d: Invalid\n",q+1);continue;}}

                 if(side1[q]==side2[q] || side1[q]==side3[q] || side3[q]==side2[q]) {printf("Case %d: Isosceles\n",q+1);}

                 else{

                 if(side1[q]!=side2[q] && side1[q]!=side3[q] && side3[q]!=side2[q]) {printf("Case %d: Scalene\n",q+1);}}

        }

    return 0;

    }

總是會把Scalene判斷成Isosceles 

與正確輸出不相符(line:5)
您的答案為: Case 5: Isosceles
正確答案為: Case 5: Scalene
 

可是明明輸入資料是三邊不等長,那我的程式碼到底是怎麼把他判斷成有兩個一樣長的呢?= =?
