CNS Practical

1. Write a C program that contains a string (char pointer) with a value ‘Hello World’. The program should XOR, AND and OR each character in this string with 0 and displays the result.
2. B. Write a C program that contains a string (char pointer) with a value ‘Hello World’. The program should XOR, AND and OR each character in this string with 127 and displays the result.
3. C. Write a C program that contains a string (char pointer) with a value ‘Hello World’. The program should bitwise OR, left shift and right shift each character in this string and displays the result.
