Question6.22:How can code in a file where an array is declared as extern。。。

那个谁

Q: How can code in a file where an array is declared as extern (i.e. it is defined, and its size determined, in some other file) determine the size of the array? sizeof doesn't seem to work.
A: See question 1.24.

那个谁

问题：代码如何判断一个用extern声明的数组的大小？（例如：它在另一个文件中定义，并且大小也确定了）sizeof此时不起作用了。
回答：参考问题1.24。
