In the C language, let's say we have a function like this: int function (int a,int b) This function can be used whenever a call is made using result = function. However, when the high-level language is compiled into machine code that

Today there are students in school asking how to get the address offset of member variables in a class, this should be a curious question for many beginners of C + +. I used to have this kind of demand when I was in school. Forget to write "strange

An indexer allows an instance of a class or struct to be indexed in the same way as an array, with an indexer similar to an attribute, unlike an indexer whose access is a parameter.Indexer and Array Comparisons:(1) The indexer has an unrestricted

The difference between a virtual method and an abstract method:1, abstract methods can only be declared in the abstract class, and the abstract method can not be implemented (cannot have method body).2. The virtual method must be implemented when
