How to divide any number by 10 using bitwise operators in C???

Answer 1

I don't think you can divide by 10 with bitwise operators. You can divide by 2, 4, 8, 16, etc with the >> (rotate right) operator though.
example:
int b, a = 200;
b = a >> 1; //divide by 2 b = 100
b = a >> 2; //divide by 4 b = 50
b = a >> 3; //divide by 8 b = 25
b = a >> 4; //divide by 16 b = 12
b = a >> 5; //divide by 32 b = 6
b = a >> 6; //divide by 64 b = 3

Answer 2

each unusual quantity (in binary) has a million on the tip ie 10001 is unusual. so do exactly if (mynum && a million == a million) unusual (mynum && a million == 0) even AND a million will positioned all flags to 0 different than final one
