Operators

• incompatible types in ?:, <type1> <> <type2> the two values returned by an arithmetic if operator have different types.

  { (1) ? "1" : 2; } /*incompatible types in ?:, char* <> int */

• pointer negation and void negation

  
  
  

• pointer complement and void complement
• ! void
• <operator> arguments have different types arguments are pointers but not of the same type.

  
  
  

• bad argument in <type1> <operator> <type2>

  { 1 - "qwe"; }

• illegal array reference when you attempt to reference an array where there is no array or int (or char) index:

  
  
  

• cast unacceptable operand of &  you cannot reference a cast. accepts cast at the left of an assignment, but it is probably too permissive.
• illegal reference

  { &1; }

• illegal indirection (not a pointer), in an access or an assignment.

  { *1; }
