Question

I have an integer in C++, and three variables. I want to put the first binary digit of it into the first variable, the second into the second and the rest into the third.

Any idea how to do it?

Answer 1

Assuming 32 bit ints:

unsigned int val = ...;
unsigned int a, b, c;

a = val & (1U << 31); // = 10000000 00000000 00000000 00000000
b = val & (1U << 30); // = 01000000 00000000 00000000 00000000
c = val & 0x3fffffff; // = 00111111 11111111 11111111 11111111
