Why does this if-statement combining assignment and an equality check return true?

Question

I\'ve been thinking of some beginner mistakes and I ended up with the one on the if statement. I expanded a bit the code to this:

int i = 0;
if          


        

Answer 1

It has to do with parsing an the right to left rules. Eg y = x+5.
All sub-expressions are weighted in importance. Two expressions of equal importance are evaluated right to left, . The && expression side is done first, followed by the LHS.

Makes sense to me.
