Write a C program that will accept a hexadecimal number as input and then display a menu that will permit any of the following operations to be carried out: Display the hexadecimal equivalent of the one's complement. (b) Carry out a masking operation and then display the hexadecimal equivalent of the result. (c) Carry out a bit shifting operation and then display the hexadecimal equivalent of the result. (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. Test the program with several different (hexadecimal) input values of your own choice.
