How to unset a specific bit in an integer

by

Assuming that you are indexing bits from the right, this should work to unset a particular bit in value:

int mask = 1 << bitIndex;
value &= ~mask;

You can set the bit using similar code:

value |= mask;

where mask is as before. (This assumes that bit indexing starts at 0.)
