数组初始化 C [英] Array initialization C

问题描述

这个初始化是什么意思:

What is the meaning of this initialization:

char arr[10] = { 0, };

我熟悉 char arr[10] = {0}; 它将所有元素设置为零，以及 char arr[10] = {1,2}; 它将前两个元素设置为 1 和 2 (ascii)，其余元素设置为 0.我不熟悉上面的格式.快速测试表明它可能就像 char arr[10] = {0};，但还有其他我不知道的含义吗?

I'm familiar with char arr[10] = {0}; which sets all the elements to zero, and with char arr[10] = {1,2}; which sets the first two elements to 1 and 2 (ascii) and the rest to 0. I'm not familiar with the format above. A quick test showed that it's probably just like char arr[10] = {0};, but is there other meaning I'm not aware of?

推荐答案

是的，相当于没有尾随逗号的版本.

Yes, it's equivalent with the version without the trailing comma.
