Question

int x=20,y=30,z=10
int i=x 15 years ago

Answer 1

if i is boolean, its value will be 1 or false

Answer 2

actually the answer of i is 1......

Answer 3

well actually it depends on the compiler. I mean, if it is left associative, it will be 1; it it is right associative it will be 0. Since most of them are left associative, calculation goes like this: x < y returns 1, then 1 < z again returns 1 because 1 < 10.
