Could someone explain this?

You may do this assignment in Java or C. I'll be more impressed if you do it in C. Write three methods or functions; if you use functions in C, make sure each function is in a separate file. M/F 1 should take a character and convert it to upper case using bitwise operators. (We went over a method for this in class.) M/F 2 should take a character and convert it to lower case. Demonstrate the running of M/F 1 and 2 by processing the string "Hello bitWise" one character at a time and printing the result (in other words, your code should build a new String character by character from the old one by using the upper and lower-case functions/methods). This assignment will be easier in C due to the simpler nature of the C character over the Java char. M/F 3 should take an int as a parameter, and return that int times 65, using bitwise operators to accomplish the task. Bonus if you check for overflow. Run this code using 101,-101, and 1,000,000,000, printing the result each time. You must submit all code, and proof that it ran
