what does this line do? especially the comma part

Question

ihi = y[0] > y[1] ? (inhi = 1, 0) : (inhi = 0, 1)

Answer 1

i understood it. here is what is happening:
basically, the syntax is
a = (b = 1, 2);
what this does is, first, it does whatever is in the parentheses, which is, first assign 1 to b then do another command which is to return 2. after that, the 2 goes to the variable a.
so now, a = 2 and b = 1.
you could do any expression separated by commas, like:
a = (b = 0, b += 2, c = 3, 1);
now a = 1, b = 2, c = 3.

Answer 2

it was in a post of obfuscated c++ code but i want to know this so bad.

Answer 3

What is inhi here?

Answer 4

an int or a bool, i suppose, because you are assigning 0 or 1 to it. but i dont know what does the "," separate. where does the remaining 1 or 0 go?

Answer 5

OK, hum may be it means a decimal number? Like 0.1 or 1.0?

Answer 6

Or may be it's a kind of struct which is composed of two values, like inhi(a, b)

Answer 7

there is a , not a . that means it is not decimal. a struct cannot be because the brackets must be { }.
thanks for the response though.
