question in C programming language

Question

I have encountered a question in C programming language and I was wrong in that question.

int x = 10, y = 20, z = 5, i;
i = x < y < z;
printf("%d\n", i);

That code outputs "1" and I can't understand why.
May anyone explain me why is i equals 1?

Answer 1

When a comparison is true it returns 1. When it's false it returns 0.

The first comparison x<y is true, so 1

The second is 1<z which is true and so 1

i = 1

Answer 2

x<y is true so it returns 1.
1<z is true so it again returns 1.

Answer 3

Ok thanks!
