Ignore negative number

Hey I need help with ignoring negative numbers when I am trying to add up only positive numbers.


SAMPLE:
if (num>=0) {
sum= sum + num;
}
else


how would the else in this case being a negative number not be included in the sum

THANKS!

You don't need an else. The if by itself is enough.

True however it would still take an inputted negative number how do i prevent that from happening.

The code snippet you posted does not "take a number". You'll have to show the code you are talking about, otherwise we can only guess.

Code:

---

if (num > 0) {
    sum += num;
}

For efficiency, the test should be greater than, because if num is 0, adding 0 to sum leaves sum unchanged.
