How do you set, clear and toggle a single bit in C?
##Setting a bit
Use the bitwise OR operator (|) to set a bit.
number |= 1 << x;
That will set bit x.
##Clearing a bit
Use the bitwise AND operator (&) to clear a bit.
number &= ~(1 << x);
That will clear bit x. You must invert the bit string with the bitwise NOT operator (~), then AND it.
##Toggling a bit
The XOR operator (^) can be used to toggle a bit.
number ^= 1 << x;
That will toggle bit x.
