遍历 C 数组 [英] Iterate through a C array

问题描述

我在程序中的某处创建了一个结构数组.

I have an array of structs that I created somewhere in my program.

稍后，我想遍历它，但我没有数组的大小.

Later, I want to iterate through that, but I don't have the size of the array.

如何遍历元素?还是我需要将尺寸存储在某个地方?

How can I iterate through the elements? Or do I need to store the size somewhere?

推荐答案

您可以将大小存储在某处，或者您可以拥有一个带有特殊值集的结构体用作哨兵，就像 \0 表示字符串结束.

You can store the size somewhere, or you can have a struct with a special value set that you use as a sentinel, the same way that \0 indicates the end of a string.
