(d) Exit. If the masking operation is selected, prompt the user lor the type of operation (bitwise and, bitwise exclusive or, or bitwise or) and then a (hexadecimal) value for the mask. If the bit shifting operation is selected. prompt the user for the type of shift (left or right), and then the number of bits.
