Which question do you think it's the most tricky one? For me, i think the last question is very tricky. It's extracted from NTU exam paper

Indeed, queston 10 is the most tricky. The rest simply test your "reading and memory".

But how come the last question answer is none of the above?
Code:
"1" + (1 + '1')


I thought (1+'1') gives you '11'. Then "1"+ '11' gives you "111"?
What's your explanation?

The correct answer is "150".
However, the process is not like what you mentioned above.

1 + '1' will give you 1 + 49 = 50 (not '11' because int> char)

"1" + (50) becomes "150"

NOTE: "1" + 1 + '1' is different from 1 + '1' + "1"

Thank you for pointing the correct way. but, isn't it round bracket takes precedent over the Plus operator? If it does, the answer wouldn't be 111, would it?
