#include<stdio.h>
int main()
{
int x=3,y,z;
y=x=10;
z=x<10;
printf("x=%d\n y=%d\n z=%d\n",x,y,z);

getch();
}

What I have tried:

output is
x=10 y=10 and z=0

why is z =0 ??

a conceptual problem

You have z = x < 10 The expression (x < 10) is false, since x == 10. In C, False is zero, and True is Non Zero.

What did you expect the value of z to be?

What did you expect the value of z to be then?!!!
Exactly the same answered by Maciej Los.

x=10, so the expression x<10 evaluate to FALSE. Since z is a type of int, the value assigned to it is zero(equivalent to FALSE).
