Simple way to set/unset an individual bit

Right now I'm using this to set/unset individual bits in a byte:

if (bit4Set)
   nbyte |= (1 << 4);
else
   nbyte &= ~(1 << 4);

But, can't you do that in a more simple/elegant way? Like setting or unsetting the bit in a single operation?

Note: I understand I can just write a function to do that, I'm just wondering if I won't be reinventing the wheel.
