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....

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...
