How to create C++ built-in type

[Klesk <kleskmail@xxxxxxxxx>]

Hi

C++ has many built-in types (int, float etc.), how to create a new
built-in type for example - how to make 'Test' defined as struct:
'Test { int a,b; };' built-in type, so that for example this code
would be correct:

int main()
{
   int x = 100;
   Test z;  // it's not defined, but it's built-in type so it should be OK
   z.a = x;
   return 0;
}
