Output question

Question

#include <stdio.h>

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

return 0;
}
How the output is 1

Answer 1

It is because you use int to declare i instead of bool and therefore True becomes 1

- - - - - - - - - - - - - - - -
1 or any value = True
0 = False

10 < 20 < 5
10 < 20 is True or 1

1 < 5
1 < 5 is True or 1

>> 1
- - - - - - - - - - - - - - - -

But it still caused an error for mathematical expression reasons. I hope this helps. Happy Coding!

Answer 2

Yeah I think in Python it does, but if you want that to happen for every compiler to be sure, just add parentheses. 10 < (20 < 5)

Answer 3

Thanks

Answer 4

Please specify a relevant language (C) in the thread's tags 👍

Answer 5

Ya but what if we check it from the right side i.e., 20<5
In some compilers they may do this

Answer 6

But I am agreed with your answer and reason

Answer 7

I think it must be compiler dependent

Answer 8

Achintya Raj Oh I forgot to say this but I think it is not recommended to use boolean expressions like that. It's still better to use &&(and) and ||(or) operators for cleaner code and to be safe and sure of the expression also.
