c++ - Argument name in function prototype -

-

In the form of an EF function declaration, three things are necessary i.e. Return value type The name of the function (argument type). But the logic name is not required when I remove the logic name ( arr [] [maxcols] ) from the function prototype ( void readMatrix (int arr [] [maxcols]) Why the program generates an error; )

In simple words. 

  Read Zero Matrix (Antar [] [Maxols]); // OK and no error zero read matrix (int); // But this error generates an error when the argument name is not mentioned in the function prototype.

Because is not related to [maxcols]

For an announcement without the name, type: 

  void f (int [] [maxcols])

and raw arrays are usually a poor choice. Use the std :: vector or std :: array .

For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
