Given float x = 10.2 and float y = 1.0. What is the value of the expression x / y?

In this scenario, you are dealing with floating-point variables where x is assigned a value of 10.2 and y holds a value of 1.0. The expression to evaluate is x / y.

When performing the division of x by y, you are effectively calculating 10.2 divided by 1.0. Since any number divided by 1 remains unchanged, the result of this operation is 10.2.

Basing the outcome on the properties of division in floating-point arithmetic, it is clear that since you are dividing a non-zero float by 1.0, the value will not change. Therefore, the expression evaluates to 10.2, which is reflected in the correct answer choice.

This reasoning highlights the fundamental principle that dividing by 1 retains the original value, making the calculation straightforward and direct in this case.
