In C, sometimes pointers are equivalent to arrays, but sometimes they are not.   When is it different? 1. the array name itself represents an address. The pointer represents the address of the address. Therefore, the definition of pointers and

Reflection definition: the ability to review metadata and collect information about its type. Metadata (the most basic data unit after compilation) is a lot of tables. When compiling an assembly or module, the compiler creates a class definition

Ref is used to directly modify the existing objects in the memory. You do not need to instantiate an object again. The return parameter is the variable value (equivalent to the pointer in C) that you can input in the function) For example Int A =
