Evaluation Rules of Postfix Expression The following are the rules for evaluation of a postfix expression: While reading the expression from left to right, push the element in the stack if it is an operand. Pop the two operands from the stack, if the element is an operator and then evaluate...
Adding postfix expressions (++ and --) Fixes add ++ and -- #17 changed evaluation order to be more human friendly (appears left to right now) remove extra () if the expression is: ident = expre e.g a = 1 + 2 instead of a = (1 + 2) before Adding postfix expressions (++ and ...
and whether or not explicit function call syntax is used), every value computation and side effect associated with any argument expression, or with the postfix expression designating the called function, is sequenced before execution of every expression or statement in the body of the called function...
The material contained in this chapter falls, roughly, into two categories: generating code for expressions and handling control-flow constructs. Expression evaluation is well explored in the literature. Discussions of how to handle control flow are rarer; much of the material on control flow in th...

14)With respect to an indeterminately-sequenced function call, the operation of compound assignment operators, and both prefix and postfix forms of increment and decrement operators are single evaluations.
