If the target language uses prefix and postfix operators, the problem is nontrivial. This paper shows how to unparse expressions using a simple, bottom-up tree walk, which keeps track of the least tightly binding operator not enclosed by parentheses. During the tree walk, this operator is ...
In Java, postfix operator has higher precedence than assignment operator, so the x++ returns the original value of x, not the incremented one. Then meanwhile x gets incremented and becomes 2. But finally x is assigned the original value returned by x++ that was 1. ...
postfix decrement operator The difference between the two is that in the postfix notation, the operator appears after postfix-expression, whereas in the prefix notation, the operator appears before expression that is for example x–; denote postfix-decrement operator and ...
Postfix: An expression is called the postfix expression if the operator appears in the expression after the operands. Simply of the form (operand1 operand2 operator). Example : AB+CD-* (Infix : (A+B) * (C-D) ) Prefix: An expression is called the prefix expression if the operator appe...

Postfix increment and decrement has higher precedence than prefix increment and decrement. The operand must have integral, floating, or pointer type and must be a modifiable l-value expression (an expression without the const attribute). The result is an l-value. When the operator appears before...
