What is type int(*)[]

I've class with matrix and getter

class A
{
  int matrix[20][10];
 public:
   auto getter(){return matrix;}
};

What is a type that auto returned? And how to return it without using auto

Auto means type is going to be decided according to what you returned. So in this case i believe it is and array that holds int arrays. You can just put the type you want to return instead of auto.

You don't really want to specify the return type without auto or a type alias. The usual rules for declarators make it quite ugly. But here it is, just follow the spiral rule:

int (*getter())[10] {return matrix;}

auto here gets the type that the function should return automatically. In that case that type is:

int (*)[10]
