What is the result of the postfix expression 8 2 / 3 +?

Options

  • A. 4
  • B. 7
  • C. 10
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. 7

Detailed Explanation

Evaluate the postfix expression from left to right using a stack. Push 8, then 2. The / operator removes 2 and 8 and computes 8 / 2 = 4. Push 4 onto the stack, then push 3. The + operator computes 4 + 3 = 7. Therefore, the final result is 7. In postfix evaluation, for a binary operator, the first popped value is the right operand and the second popped value is the left operand.
