As we all know, in the C language, the fields in the struct are accessible. Or, in C + +, the main difference between classes and structs is that the member variables in the class default to private, whereas the struct defaults topublic. This

Calling C/C + + generated DLL files for the first time is a bit fresher, and it's actually just something that implements "unmanaged code" that executes outside the control of the Common Language execution library (CLR), which is called "managed

C + + language is one of the widely used programming languages, because of its unique advantages in the Computer application field occupies an important seat.The development of C language In the early 1970s, Dennis Richie of Bell Labs

Because C + + supports function overloading, when compiling the function code, the parameter type information is added, and C compiles only the function name information, which causes C + + to call C code directly when the function is not defined in
