The fifth day of learning C language

It's not a document or a tutorial. It's just supervising myself to learn C language by clocking in and recording only some small notes. If there is any mistake, thank you very much for pointing it out! ! !

1. Structure

• The memory alignment of the structure is based on the data type in the structure
• #pragma packZ(), you can set the alignment
• c11 supports _Alignas(), _Alignof (structure. Variable name)
• Use (#include<stddef.h>), offsetof (structure, variable name) in msvc

2. Consortium

• Same as structure, but will share

I learned very little today, just criticize
