Hi Experts, - I am trying to get output of exponent of a and b 's sum. Can you please advise why getting wrong output here: Code: $ cat t1.c #include <stdlib.h> #include <stdio.h> main (){ int a,b,c,d=2;int r; /* Integers */ [COLOR="Green"]r=(a^2+b^2)[/COLOR]; printf ("Hello:int practice ..: int a,b,c,d :: r=%d\n",r); exit(0); } Code: ./t1 Hello:int practice ..: int a,b,c,d :: [COLOR="Red"]r=32771[/COLOR] - Value of r should be 8 , instead of 32771 , right .. Thanks,
Not quite; you're using unitialize values for both a and b, but there's more. ^ the xor operator and not square; the code you've posted gets interesting... without inner parens, you may get a side effect from the addition along side the value of xor operation Code: int a = 2, b = 2, r r=(a^2+b^2); // 2^2 + 2^2 // 010 // xor // 010 // ------- / 000 0 + 2 + 2 + 0 = 4 If you want the square, create your own function or maybe include math.h and use pow.
