Enum provides the base class for enumerations, whichbase TypeCan be any integral type except Char. If you do not explicitly declare an underlying type, use Int32. Programming languages typically provide syntax to declare enumerations that consist of

For those of you who are accustomed to using C for development, you may be confused when you see the & symbols appearing in C + +, because in c the symbol represents the fetch address character , which is often used to assign values to pointers in

When we learn spring, we know that spring has two main ideas, one is the IOC, the other is AOP, and for IOC, dependency injection doesn't have to be said, and for spring's core AOP, we not only need to know how to satisfy our function through AOP,

What: What is dynamic memory?In C + +, the normal variable (non-static object) is stored in the stack memory, static variables (local static, class static) are stored in static memory, there is another memory pool in the system, this part of the
