If you want to use a function across multiple source files, you should declare the function in one header file (.h) and then put the function definition in one source file (.c or .cpp). All code that uses the function should include just the .h file, and you should link the resulti...

In this expression, we write the “#define” command for a function or a prolonged-expression for one or more variables and name it accordingly. Now that we know what the roots are of the “#define” preprocessed commands and where it is used, we can move on to the implementation part ...

I'm maintaining a C program (have added some C++ to it). One source file defines an array of data that was local to that module. I need to expose that array to other modules. Recognizing that global variables are generally discouraged, how best to accomplish this?
同样,class.cpp被编译成class.obj文件。为了生成最终的可执行文件,将调用链接器以将这两个目标文件链接在一起。对于任何未解析的外部变量或函数,编译器将在存根位置放置一个存根 (For any unresolved external variables or functions, the compiler will place a stub where the access happens.)。然后,链接器将...
