Answer:
Option (A) int expressions are always computed exactly; but float expressions can suffer round-off error.
Explanation:
Round - Off Error can be defined as the digital computers have limitations on denoting the decimal numbers, due to this the floating point numbers have to be rounded off or even it is represented exactly after the calculation on the numbers the resulting number has to be adjusted / rounded off according to the specified precision. The resulted number has to be rounded off back to the required precision, this leads to the round off errors in digital computers. As integers don't need to go through the rounding off in computers, the integer numbers don't have round off errors, only floating point numbers have round off errors. So, options (B) , (C) and (D) are false.

Let's say you entered 1 for x and 0 for y, first if statement will print hi, but the second one will not print because x is not smaller or greater than 0.
Let's say you entered 0 for x and 6 for y, second if statement will print hi, but the first one will not print because x is not greater than 0.
