Task No. 1 about integer type conversions

12
Locked

This task begins a series of tasks about integer type conversions. This is not a very difficult topic, but it often bewilders noobies because instructors sometimes put in at the very beginning, which is fundamentally wrong. But on Level 10, you're ready. Arrange the cast operators correctly to get the required result: d > 0. The operators are in the conditions.

Can someone explain to me how the expression ( a + b / f + c ) doesn't trigger a division by zero? Doesn't the division have higher priority than the 2 additions?

hint: one type only allows positive numbers, so if d is that type...then done

what i don't understand is why changing every other cast operator results in a negative number?

I think line 8 should say: "8. Don't change the initial value of the variables during initialization. You can only add or change cast operators. I got this right but I am also curious why this program does not error out (or show "Infinity") as "f / c" is dividing by 0 as this is the first operation to be performed. It keeps showing -1 which just does not make sense to me.

For infinity, perhaps, when the wrap around is taking place, it is assuming a value of -1 in short data type.
