int a = 100;
What would the following return?
int b = a > 5 ? a > 10 ? 10 : 5 : 0;

1This is something you can test yourself. Just run your code and observe the results. – Sam Axe May 26 '18 at 17:57

1Your question is essentially a dupe of this one, which has a good answer by Konrad Rudolph: https://stackoverflow.com/q/1763543/ – Max Barraclough May 26 '18 at 18:00

You can rewrite what you just wrote like this:
a > 5 ? ( a > 10 ? 10 : 5 ) : 0
After all, there is no other way you could arrange the parentheses that would make sense. Therefore, the a > 5 comparison must be tested first because if a > 5 does not evaluate to true, then the second comparison is not necessary.

Your code is missing the first ?. a > 5 ? ( a > 10 ? 10 : 5 ) : 0 – Pedro Fernandes May 26 '18 at 18:03
