The EvaluationOrder/Precedence of C/C++ Operators.

[Jeff-Relf.Me]

The Evaluation Order of these expressions are UnDefined/SemiRandom:

  i = ++i + i++ ;     i = i++ + 1 ;             Array[ i ] = i++ ;
  Func( ++i, ++i );   Func( i = -1, i = -1 );   Func( i, i++ );

The middle part of a Conditional Expression ( between ? and : )
is parsed as if parenthesized; for example:

  int rv, zz ;

  zz = 1, rv = zz ? zz = 1, 2 : zz = 3, 6 ;
  printf( L"%d and %d", rv, zz );  //  Prints: " 2 and 1 ".

  zz = 0, rv = zz ? zz = 1, 2 : zz = 3, 6 ;
  printf( L"%d and %d", rv, zz );  //  Prints: " 3 and 3 ".
