Powers in c?

sorry to bother you all again, but I am struggling with powers in c.


#include %26lt;iostream%26gt;


int main(){


for (int i = 0; i %26lt; 20; i++){


printf("2 ^ %d = %d \n", i, 2^i);


}


}


returns


2 ^ 0 = 2


2 ^ 1 = 3


2 ^ 2 = 2...





what am I doing wrong? and what is the ^ opperator if not power?

Why don't you use the function pow(x,y) in %26lt;math.h%26gt;??


"^" is a bitwise operator (XOR)
Reply:^ I think is a bit-wise operator in C.





There is no exponent function native in C unless one's burried in the math libraries.





But I think this excersize is supposed to force you to create the function, passing in x and y).
