infixpostfixWe show that a particular algorithm for the translation of arithmetic expressions in infix form into postfix form is correct. The method used is ad hoc, in contrast to other work in this field, and it is hoped that this in itself is of interest....

中序式转后序式(前序式) 说明:平常所使用的运算式,主要是将运算元放在运算子的两旁,例如a+b/d这样的式子,这称之为中 序(Infix )表示式,对于人类来说,这样的式子很容易理 解,但由于电脑执行指令时是有顺序的,遇 到中序表示式时,无法直接进行运算,而必须进一步判断运算的先后顺序,所以必须将中序表示式转换...

A unary minus sign does not cause any operators to be popped from the stack. This is because, in the postfix output, the unary minus sign will always immediately follow its operand (whereas it always immediately precedes it in the infix), so no other operators can be popped before it at...
