我用tc编译了
没有问题啊
这是我运行的结果
*********
score[0][0]= 0.00score[0][1]= 0.00score[0][2]= 0.00score[0][3]= 0.06
score[1][0]= 0.00score[1][1]= 0.00score[1][2]= 0.00score[1][3]= 0.06
score[2][0]= 0.00score[2][1]= 0.00score[2][2]= 0.00score[2][3]= 0.06
sum=778.00
avarage=64.83
score[2][0]=60.00 score[2][1]=50.00 score[2][2]=80.00 score[2][3]=70.00
这个应该发到计算机编程分类，怎磨跑物理学来了？
