Difference between struct and class The most important thing is the difference between value and object. However, it is very important to find another interesting phenomenon recently. In a project, struct is used because of various structures.

Now we are working on a semantic extraction task. For example, extract all public content from a class. 1. Ensure that the input string is a valid class and starts with class XXXXX {and ends }; 2. Make sure that each permission (public,
