问题描述
我想知道为什么引入了结构对齐规则。
有/无边界对齐的结构有何不同。
问候

Hi,
I would like to know why structure alignment rules were introduced.
How does a structure with/without boundary alignments differ.

推荐答案
一般来说，与今天的内存系统数量相比，这种浪费相对较低（每个结构几个字节）。因此，除非你有很多这样的结构，否则浪费可能是微不足道的。
如果你有大量的结构或有限的记忆，那么减少这种浪费可能是明智的。你可以通过仔细制作你的结构来做到这一点，举个例子
Generally speaking this wastage is relatively low (a few bytes per structure) compared to the amount of memory systems tend to have today. So unless you have a lot of those structures the wastage is probably negligible.
If you have a very large number of structures or limited memory then reducing this wastage may be sensible. You can do this by crafting your structures carefully, take this example
