好的，所以我有2个阵列，一个由20支球队组成，另外一支由联盟赛程组成。然后，我有一个非常大的for循环，它循环遍历每个单一的夹具，并为每个团队分配得分，目标得分，目标允许等。只要夹具阵列中没有超过20个夹具，一切都能正常工作。一旦我将第21个灯具放入阵列中，我的桌子就崩溃了，我不知道为什么。

points for all teams

答案 0 :(得分：1)
您可以在某些地方执行类似
的操作teams[j].GD = teams[i].GF - teams[i].GA;
现在，i是fixtures的索引，而j是teams的索引
因为你有20支球队和21支球队，当j == 20（第21指数）球队[i]将被定义
