Show the before and after of the code you refactored b. Explain what you identified as needing improvement and describe how your refactored code is improved in style and behavior (if applicable) You should answer this question on your own sheet(s) and attach the answer (electronically) to the PDF document you use to submit the answers to questions 1-4. Please follow the format below in your answer. If your code will not fit side by side (which is perfectly fine) please put before first, and then after second, followed by your explanation Example format: Before After void do_everything) /1 do thing 1 // if thing 1 worked bool do_thing1().; void do thing2(); void do thing3(); // do thing 2 // finally do thing 3 int main(void) (do, thing!()) do_thing2(); if { int main (void) - do_everything(); do_thing3); Here you will explain what were some of the problems you identified with the original code and what improvements did you get from your refactored code
