英文:
C++: Is there a case when a struct can have different sizes depending on the endianness?
问题
我在一本教材上看到，当字节序更改时，结构体的大小可能会发生变化。我不确定，但我认为示例是
struct X { int a, char b };
请有人解释一下这是否正确？
英文:
So I read on a textbook that there are specific cases when the struct can change sizes when the endianness is changed. I am not sure, but I think that the example was
struct X { int a, char b };
Can someone explain if this is true ?

A change in endianness means you are on a different system where the compiler is free to define padding, integer size and byte size which could all lead to a different struct size, but it would not be because of the endianness.
