Question

Hello I need help in a C++ program. On line 30, the reference variables are getting errors because there's an expected primary expression but I'm not sure what they are. What's underlined below are the errors.

ReadRoomData(int &room_num, int &max_cap, int &enrolled);

Text files:

roomset_one.dat
- 426 25 25
  327 18 14
  420 20 15
  317 100 101

roomset_three.dat

Program Requirements

DO NOT open the file and use it within your program (input redirection)
- Example of input redirection: ./a.out < roomset_one.dat
You must include the following functions:
- ReadRoomData: a void function that accepts three reference parameters (the room number, max capacity, and enrolled). It should read in all three values from stdin.
- DetermineStatus: a value-returning function that has one parameter (available enrollment). It should return a std::string containing the status of the room (OPEN, FULL, OVER)
- OutputRoomInfo: a void function that accepts three value parameters (room, max capacity, and enrolled). It should call DetermineStatus and output the formatted room information for that single set of data.
