circular-dependency

You can structure a C++ program so that (almost) all the code resides in Header files. It essentially looks like a C# or Java program. However, you do need at least one .cpp file to pull in all the header files when compiling. Now I know some people would absolutely detest this idea. But I haven't found any convincing downsides of doing this. I can list some advantages: [1] Faster compile times. All header files only get parsed once, because there is only one .cpp file. Also, one header file cannot be included more than once, otherwise you will get a build break. There are other ways of

I have two classes, foo and bar . foo.h #include s bar.h and contains a std::vector of pointers to bar objects. At some point during runtime, bar has to access this vector of pointers to other bar objects. Therefore, foo contains a method named getBarObjects() that returns the array of pointers. Therefore, I forward declare foo in bar.h. I obviously also have to forward declare the method I'm using - foo::getBarObjects() . As this returns the array of pointers to bar , I get into a vicious cycle. I cannot forward declare Bar and then simply forward declare getBarObjects() , as this results in

I've been struggling around injecting services into each other. The following blog Circular Dependency in constructors and Dependency Injection is kind of confusing where it says One of the two objects is hiding another object C I get the following error while injecting Service class into each other Can't resolve all parameters for PayrollService: (SiteService, StorageService, SweetAlertService, ?) //abstractmodal.service.ts @Injectable() export abstract class AbstractModel { abstract collection = []; constructor(private siteService: SiteService, private storageService: StorageService, private

What is the best way to resolve the following circular dependency in typedef-ing these structs? Note the C language tag - I'm looking for a solution in standard gcc C. typedef struct { char* name; int age; int lefthanded; People* friends; } Person; typedef struct { int count; int max; Person* data; } People; Forward-declare one of the structs: struct people; typedef struct { /* same as before */ struct people* friends; } Person; typedef struct people { /* same as before */ } People; The answer lies in the difference between declaration and definition. You are attempting to declare and define
