Note points for chained storage in data structures (linear vs. Stacks)

When passing data to complex type data, you can directly pass the first address of the business data to the bottom of the business layer, and the underlying layer can be directly offset by four bytes to concatenate the elements of the business tier.

The underlying can directly use the memory space allocated by the business layer,

When passing data as the underlying type of data, the above approach is not available, and another idea is to create a new node structure at the bottom, a pointer field, a data field, and pass data from the business layer to the underlying data field (usually the void * type).
