One important bitwise operation not discussed in the lab is bitwise negation (inversion). This can be performed using the "exclusive-or" operation (implemented with "^" in C). Suppose I want to invert the most significant bit in a byte of data but leave the other seven bits unchanged. How to write C function that takes a byte of data as an argument and uses a bitmask, and an exclusive-or to invert the most significant bit of that data.
