Question
Assume y be an array. Which of the following operations are incorrect?
I. ++y
II. y + 1
III. y++
IV. y * 2
a. I and II
b. I, II and III
c. II and III
d. I, III and IV
Solution
To determine which of the operations are incorrect, let's analyze each option step by step:
I. ++y: This operation increments the value of y by 1. It is a valid operation and does not have any issues.
II. y+1: This operation adds 1 to the value of y. It is also a valid operation and does not have any issues.
III. y++: This operation is a post-increment operation, which means it increments the value of y by 1 after the expression is evaluated. It is a valid operation and does not have any issues.
IV. y*2: This operation multiplies the value of y by 2. It is a valid operation and does not have any issues.
Based on the analysis, all of the given operations (I, II, III, and IV) are correct. Therefore, the correct answer is d. I, III, and IV.
