The main difference between process-oriented design and object-oriented design is whether to use lengthy if else judgment at the business logic layer. If you are still using the if else in large quantities, except for the interface presentation

What is alignment and why:In modern computers, memory space is divided by byte. Theoretically, it seems that access to any type of variables can start from any address, however, the actual situation is that access to specific variables is often
