Operator Precedence vs Order of Evaluation http://stackoverflow.com/questions/5473107/operator-precedence-vs-order-of-evaluation is what is said in this MSDN Article The precedence and associativity of C operators affect the grouping and evaluation of operands.. an operator x y z is same as x y z . My reasoning is if associativity does not come into play then the complete expressions evaluation.. operators in order of precedence highest to lowest . Their associativity indicates in what order operators of equal precedence in an..
