Question

I have some logic that I would like to store as an integer. I have 30 “positions” that can be either yes or no and I would like to represent this as an integer. As I am looping through these positions what would be the easiest way to store this information as an integer?

Answer 1

You can use a 32 bit uint:

uint32_t flags = 0;
flags |= UINT32_C(1) << x; // set x'th bit from right
flags &= ~(UINT32_C(1) << x); // unset x'th bit from right
if (flags & UINT32_C(1) << x) // test x'th bit from right
