Answer Posted / Balram
In C programming, portions of a program can be disabled in demo versions through various techniques. Some common methods include: (1) Compiler directives like #ifndef, #define, and #endif to conditional compile specific code sections based on preprocessor symbols, (2) Dynamic function loading and selectively not loading crucial functions for the demo version, and (3) Using conditional compilation flags provided by the build system to control whether certain features or functions are included in the final compiled binary.

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.
