Question

what is x after the following statements? int x = 2; int y = 1; x *= y + 1; a x is 4. b x is 3. c x is 2. d x is 1.

Explanation:

Step1: Analyze the initial values

We have \( \text{int } x = 2 \) and \( \text{int } y = 1 \).

Step2: Evaluate the expression in the assignment

The statement is \( x *= y + 1 \), which is equivalent to \( x = x * (y + 1) \). First, calculate \( y + 1 \): \( y + 1 = 1 + 1 = 2 \). Then, multiply \( x \) (which is 2) by this result: \( x = 2 * 2 = 4 \).

Answer:

A. x is 4.
