The statement is not equivalent to count = count + 2. True or False?

• A. False
• B. True
• C. Sometimes
• D. Cannot determine

Answer: (A)

The key idea is how assignment updates a variable. count = count + 2 takes the current value of count, adds 2 to it, and then stores that result back into count. The shorthand count += 2 does exactly the same thing: it adds 2 to the current value and assigns it back. So these two forms produce the same final value for count.

Saying they are not equivalents is incorrect, so the statement is false. The only nuanced point is that in some contexts the value the expression yields might differ (for example, inside a larger expression), but the actual update to count is the same in both forms.
