I see no need to optimize integer increments.
My loops look like this:

  wchar _T[999], *P = _T ;

  Loop(3) { int Y = J ;
    Loop(4) P += Str( P, L"( %d, %d )%s", J, Y, J == LLL - 1 ? L"\n" :  L" " );  }

  printf( _T );

Given:

  #define  Loop( N )  int LLL = ( N ), J = -1 ; while ( ++J < LLL )
  #define  StrF  fwprintf
  typedef  wchar_t  wchar ;

Output:

  ( 0, 0 ) ( 1, 0 ) ( 2, 0 ) ( 3, 0 )
  ( 0, 1 ) ( 1, 1 ) ( 2, 1 ) ( 3, 1 )
  ( 0, 2 ) ( 1, 2 ) ( 2, 2 ) ( 3, 2 )
