The given program prompts the user to enter a password and then to confirm the password. A function check_password determines if the password meets the criteria. The code is not yet finished. Complete the program and make sure it compiles with NO warnings or errors. The password rules are in the function comment of check_password The program should use the return value from 'check_password' to notify the user depending on which error code is received. If the password is validated, print "Password accepted." . If the password does not meet the required length, print "Password must be 8 characters." If the password does not match the confirmation password, print "Passwords must match." If the password does not contain a number, print "Password must contain at least 1 number." If the password does not contain an uppercase character, print "Password must contain at least 1 uppercase character
