推荐答案

您真的不能从C删除的元素++数组。

You can't really "delete" an element from a C++ array.

但是，如果阵列由指针，你可以删除对象，特定元素点。

However, if the array consists of pointers, you can delete the object that a specific element points to.

在你的老师的情况下，这将是重要的是要注意是否数组的对象是动态分配的（使用新 C ++操作符）或没有。他可能只是作为一个指标，该值就不再有效了值设置为 0 。

In your teacher's case, it will be important to make note of whether the objects of the array are dynamically allocated (using the new operator in C++) or not. He may simply be setting his values to 0 as an indicator that the value is no longer valid.

如果没有实际的源$ C ​​$ C，这就像我可以帮你。

Without actual source code, this is as much as I can help you with.
