Question
What is the outcome of the prefix expression +, -, *, 3, 2, /, 8, 4, 1?a.10b.11c.5d.4
Solution
The prefix expression is evaluated from left to right. Here are the steps:
-
The first operator is '+'. It needs two operands. The next operator is '-', which also needs two operands. So we move further.
-
The next operator is '*'. It needs two operands, which are 3 and 2. So, we perform the multiplication: 3 * 2 = 6.
-
Now, we go back to the '-' operator. It has one operand now (6 from the previous step), but it needs one more. The next operator is '/', which needs two operands, which are 8 and 4. So, we perform the division: 8 / 4 = 2.
-
Now, the '-' operator has its two operands: 6 and 2. So, we perform the subtraction: 6 - 2 = 4.
-
Finally, the '+' operator has its two operands: 4 (from the previous step) and 1. So, we perform the addition: 4 + 1 = 5.
So, the outcome of the prefix expression is 5. Therefore, the correct answer is c.5.
