c++ - What's the difference between namespaces & classes? -

-

In C ++ 13/4 environment, what is the difference between a namespace and a square?

The way I see it; 

  named place foo {int a: 4; Int b: 4; }

and 

  class bar {public: int a = 0; Int b = 0; }

The same thing ...

Yes, they are used differently;

Namespace .... 

  foo :: a = 20; Foo :: b = 30;

class .... 

  bar alpha; Alpha. A ... Alpha B ...

But in general, what is the advantage of one over the other?

There are a lot of differences, there is a group system for namespace names, more or nothing less

  • can be done quickly.
  • can be obtained from.
  • Virtual tasks can be.

    • And so on.

    If you think yourself whether you should use namespace or a class, then you are probably exploring a way to control the scope of names - so the election is clear: Nameshot's Use the.

    Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? 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.
