--- Comment #5 from Walter Bright <bugzi...@digitalmars.com> 2010-03-04 02:40:29 PST --- C99 says this about ++x: -------6.5.3.1------------- The operand of the prefix increment or decrement operator shall have qualified or unqualified real or pointer type and shall be a modifiable lvalue. Semantics The value of the operand of the prefix ++ operator is incremented. The result is the new value of the operand after incrementation. The expression ++E is equivalent to (E+=1). See the discussions of additive operators and compound assignment for information on constraints, types, side effects, and conversions and the effects of operations on pointers. The prefix -- operator is analogous to the prefix ++ operator, except that the value of the operand is decremented. --------6.5.16------------------- An assignment expression has the value of the left operand after the assignment, but is not an lvalue. --------------------------------- It is equivalent to x+=1, and therefore not an lvalue. The C++98 spec also says that ++x is equivalent to x+=1, but says that the result of x+=1 is an lvalue. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
