Question
Which of the following is an example of Postfix expression?
- a.
AB C ^ / D E * + A C * - - b.
.*+ABC - c.
None of these - d.
(A + B) / C
Solution
The correct answer is b.*+ABC. This is an example of a postfix expression.
Postfix expression, also known as Reverse Polish Notation (RPN), is a mathematical notation in which every operator follows all of its operands. In other words, the operator is postfixed to the operands.
Here's why b.*+ABC is a postfix expression:
- The expression can be read as: "A and B are added together, then the result is multiplied by C".
- The operators (+ and *) come after the operands (A, B, C).
The other options are not postfix expressions:
- a.AB C ^ / D E * + A C * - : This is not a valid expression in any notation.
- c.None of these: This is not an expression.
- d.(A + B) / C: This is an infix expression, not a postfix expression. In infix notation, operators are written between the operands.
