Given float x = 10.2 and float y = 1.0, what is the value of the expression x / y?

The expression x / y evaluates the division of two floating-point numbers. In this case, x is assigned the value 10.2 and y is assigned the value 1.0. When performing the division, you are essentially calculating how many times y fits into x.

Since y equals 1.0, dividing any number by 1 results in the original number itself. Therefore, 10.2 divided by 1.0 yields 10.2. This operation retains the floating-point representation of the numbers involved, resulting in a floating point value of 10.2.

Thus, the value of the expression x / y is indeed 10.2. This understanding of division and the behavior of floating-point arithmetic is essential for grasping how similar expressions would evaluate in programming.
