Write a program that stimulates a questionnaire to find a ro

Write a program that stimulates a questionnaire to find a roommate from your CIS 121 Course class. You will ask the user various questions that might determine a suitable match, at least 5 conditions satisfied from the potential questions. Store the names of students who matches your preference in a file called matchfile. Also, store names of students who are not your preferred match in one-dimensional array called NoMatch, size 21.
