Hello, this program is used to calculate the occupancy rate, total amount of rooms, total amount of occupied rooms, and total amount of vacant rooms, all in a hotel. The inputs are the amount of floors, the amount of rooms per floor, and the amount of occupied rooms on a given floor. After the input data is entered, the occupancy rate always comes out to 0.0 which is my problem. I have a feeling that the problem lies in my variable counters named: occRoomsT and roomNoT.
Just make,
occupancyRate = ((double)occRoomsT) / roomNoT;
Total number of rooms will always be an integer and declaring them as double is not a good practice and this occupies more space compared to an integer.
