C and C + + mixed, C call c++,c++ call C

These two days have been addressing such a problem, the project has the following requirements: Embedded products, the algorithm part of the implementation of C + +, while the control program and other programs with C implementation. This requires that the C + + algorithm can be invoked through the program. At the same time, the project has a PC demo program,

C Language/c++ Programming Learning: Do not work in C + + to learn the reasons for C + +!

C language is process-oriented, and C + + is Object-orientedThe difference between C and C + +:C is a structured language that focuses on algorithms and data structures. The design of the C program is primarily concerned with the

The Visual C + + compiler automatically assumes the band. C file extension is a C file instead of C + + file, and C + + syntax and keywords are rejected (C language can only declare variables at the top of curly braces)

Today, when compiling OpenGL Red Book with the light.c file in the source code, you encounter a strange problem:Light. c, compile OK without making any changes. However, if you write executable code in some places, you will not be able to compile through the compiler!(These lines of code are OK if the first sentence in the main function is written)I used the VS08. I sent the document to other friends (VS10), which is the same problem.However, after I

Static calls in C # C++dll and C # in dynamic call C++dll

C \ c ++ DLL-> C #-> maxscript calls the DLL written by C ++ through C #

It's actually the old post of a previous blog. If you haven't written a blog for too long, paste it. Since max9, maxscript can directly call. Net DLL files and create classes to use the methods. And. Net can call the DLL file written in C ++. Therefore, you can use C # to encapsulate the C ++ code and call it in Max. The following is an example. --------------- B

C and C + + mixed programming (use of __cplusplus and external "C")

The first kind of understandingFor example, you have developed a DLL library in C + +, in order to enable the C language to call your DLL output (export) function, you need to use extern "C" to force the compiler not to modify your The name of the function. In general, you can often see code similar to the following in the header file of the
