very simple doubt

[scofield]

Hello all, i'm trying to get the result of an expression using the exponential (^) but it returns wrong values:

printf("%d\n", 3^0);
printf("%d\n", 3^1);
printf("%d\n", 3^2);

output:

3
2
1

Do you know what i'm doing wrong? I'm using gcc compiler.
Thanks.

The ^ is the exclusive or operator in C, not exponential notation.

That's not exponential, it's a bitwise xor operator. For exponential, include <math.h> and use pow().
