Given integer x = 3 and integer y = 5. What is the value of the expression (x / 2.0) + y?

To determine the value of the expression (x / 2.0) + y given the integers x = 3 and y = 5, we first need to evaluate (x / 2.0).

In this case, x is 3. When we divide 3 by 2.0, the presence of the decimal point (2.0) indicates that the operation is performed in floating-point arithmetic rather than integer arithmetic. This means that instead of truncating any decimal part, the calculation yields a precise decimal result. Thus, 3 divided by 2.0 gives us 1.5.

Next, we add this result to the value of y, which is 5. So, we perform the addition:

1.5 + 5 = 6.5.

Therefore, the result of the entire expression (x / 2.0) + y is 6.5, making it the correct answer.

Understanding how floating-point division works in contrast to integer division is crucial, as it directly impacts the outcome when dealing with numbers that can result in decimals. This knowledge applies broadly in programming, mathematics, and scenarios involving precise calculations.
