7. The following problems deal with working with bit masks. (a) Define an 8 bit mask that you can use with a binary operator to set the MSB of an 8 bit value to 1, leaving all the other bits as they were. Example: Given 01101101, your mask when applied should result in 11101101. What operation do you need to use with the mask you designed? (b) Determine the hexadecimal value of a mask that can be inclusively ORed with the bit pattern in flag to reproduce the fifth and seventh bits of flag and set all other bits to one. Again, consider the rightmost bit of flag to be bit 0. (c) Determine the hexadecimal value of a mask that can be used to complement the values of the first and third bits of flag and leave all other bits unchanged. Determine the bit operation that should be used with the mask value to produce the desired result. 7. The following problems deal with working with bit masks.
