C++

For the assignment, we will use the previous assignment’s program that determines whether a college class room is in violation of fire law regulations regarding the maximum room capacity and add more logic to that program. We will need to make the following enhancements…

For each new class entry that is taken, you will write out the information to a file. The file can be any .txt file name of your choosing. The file should be appended to each time the program runs (see app mode). The format of the file should be as follows:
- Begin each new line or record with the name of the class room
- Next, add the attendance for the first entry
- Follow that with the total possible attendance for the first entry
- Continue adding each attendance and possible attendance for the subsequent entries until you reach the last one

That’s it. Be sure to format this file so you can also read it later.

Remember, the program continues doing everything that it did before, plus these enhancements. Match your program with the sample output as shown below.

Your choice:

(assume user enters 4…)

Whitby Hall room 111 has capacity for 75.

(assume computer randomly generates 3…)

Enter the number of attendees: 72

It is legal to hold class and there is minimal 4% capacity remaining

Enter the number of attendees: 92

The class cannot be held as planned

Enter the number of attendees: 75

It is legal to hold class and there is minimal 0% capacity remaining

… the file for the example above might look like this …

Whitby Hall room 111 72 75 92 75 75 75

Make sure that your programs follow good documentation standards and follow the requirements for assignments. Reference the rubric standards on Brightspace. Do not use namespace std.
