For the following three questions, remember that bit numbers start numbering from 0, and that hexadecimal numbers are always unsigned. In addition to showing the mask you would use, also show the operation you would use, like so: &0x0020. (i.e., AND the original number with the hexadecimal mask 0x0020.) 42.) Specify the mask you would need to inspect bit 5 of the unknown number. Express it as a 4-digit hexadecimal number. 43.) Specify the mask you would need to set bit 5 of the unknown number to zero. That is, the result of this operation results in a new number, which the unknown number should be subsequently set to. Express it as a 4-digit hexadecimal number. 44.) Specify the mask you would need to set bit 5 of the unknown number to one. That is, the result of this operation results in a new number, which the unknown number should be subsequently set to. Express it as a 4-digit hexadecimal number.
