Q. 3. Evaluate the postfix expressions. Use the algorithm to evaluate postfix expression (page - 373). You MUST show the steps (contents of the stacks) to get full credit. Assume a = 6.0, b = 1.0, c = 3.0, and d = 4.0 Postfix expression: a b c - /d - Step Expression Status of the Operand Stack Calculation 1 a b c - /d - Top = -1 2 bc - d - 3 c - /d 4 - / d - 5 / d - 6 d - 6 End of expression (Answer) 7
