推荐答案

你不能真正从 C++ 数组中删除"一个元素.

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

但是，如果数组由指针组成，则可以删除特定元素指向的对象.

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

在您老师的例子中，重要的是要注意数组的对象是否是动态分配的(使用 C++ 中的 new 运算符).他可能只是将他的值设置为 0 作为该值不再有效的指示.

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 He may simply be setting his values to 0 as an indicator that the value is no longer valid.

没有实际的源代码，我能帮到你的就这么多了.

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