Output the display of what the functions do by calling them and printing them inside your main function. This can also be used to confirm that all your functions work correctly. For the bit array you can either display both initial and result or find another way to get input into your bit array. | Output the display of what the functions do by calling them and printing them inside your main function.

=====VERIFICATION===== | =====VERIFICATION===== | ||
There is no make verify with this project. Your verification can be in the form of the main function displaying the truth tables. You can also display the rotate left and right array values after calling your function. The truth tables are located above to refer to. | There is no make verify with this project.
