OutStream problem

jzilliam (40)
This is actually a followup to my last post

So I have this list of titles, dates, times, and durations and I managed to get all them to to output in an orderly fashion however there seems to be some problems with the time in particular.

Also I need these 5 functions for argc-argv however I cannot do this yet because the time is kind of screwed up (specifically with pm):

• ./a.out -ps
o Print my daily schedule in order by starting time using standard time format. The
appointments must be displayed in a table format with proper labels.
• ./a.out -p "time"
o Print all appointments at specified military time.
• ./a.out -a "Appointment data"
o Add an appointment given in the format:
"title|year|month|day|time|duration".
Time is given in standard time and duration is given in minutes. Leading and
trailing spaces must be removed.
Example: " Meeting with Bob | 2019 |4 |29 |8:30 aM |15 "
• ./a.out -dt "title"
o Delete all appointments that match a title exactly. It should work for both upperand lower-case characters with leading and trailing spaces removed.
• ./a.out -dm "time"
o Delete a all appointments that match the starting military time exactly.

Output I have at the moment:

^ Decent but not quite the best

There is only the one error now correctly reported - invalid month.

Oh Thank you! Also how would you got about sorting the times so that the entire lines are printed in order

I'm just trouble with sorting the entire line:

1
2
3
4
5
6
7
8
9
10
 
if (option == "-ps") //All "-ps" is a command line arg
    {
        while (getline(inStream, line))
        {
            if(!line.empty()){
                //Something to do with printing the sorted timeline
            }
        }
        
    }


TLDR: Basically I'm trying to sort the schedule in order of time

UPDATE: I managed to make a code for the -p function however the output may be a bit iffy:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

20
21
22
23
24
25
26
27
28
29
30
31
32
 
const string fileName{"agenda.txt"};

    ifstream inStream(fileName);
    string option = argv[1];
    int timeState = atoi(argv[2]);

    if (!inStream)
        return (cout << "Error: file not found " << fileName << '\n'), 2;

    for (string line; getline(inStream, line);)
        if (!line.empty())
        {
            const Appointment myApp{line};

            if (myApp.isvalid())

                if (option == "-ps") //This Doesn't Work at the moment
                {
                    for (size_t i = 0; i < myApp; i++)
                    {
                        sort(myApp.getTime().begin(), myApp.getTime().end());
                    }
                }

            if (option == "-p") //Works!
            {
                if (myApp.getTime() == timeState)
                {
                    cout << myApp << endl;
                }
            }
        }


The output:

If you want to sort the appointments by time (or any other element), then you're going to have to store the appointments in a container (probably a vector) and then sort by date and then by time. Something like:

Would you know how to convert an entire string to lowercase? I've attempted it here but got some errors
seeplus (6591)
re the sort. If you provide a member function to return the date as a number in the format yyyymmdd, then the sort can be simplified:

1
2
3
4
5
6
7
8
9
10
11
12
13
 
unsigned getnumDate() const;
...
unsigned Appointment::getnumDate() const {
	return year * 10000 + month * 100 + day;
}
...
sort(apps.begin(), apps.end(), [](const auto& a, const auto& b) {
		if (a.getnumDate() < b.getnumDate()) return true;
		if (a.getnumDate() == b.getnumDate())
			if (a.getTime() < b.getTime()) return true;

		return false;
		});

seeplus (6591)
This will convert a string to lowercase:

1
2
3
4
 
void toLower(string& s) {
	for (auto& c : s)
		c = static_cast<char>(tolower(static_cast<unsigned char>(c)));
}

jzilliam (40)
Seeplus, I don't think it would be necessary to sort with the date included as all the days, months, and years are exactly the same. I'm just worried about sorting ONLY the time here and nothing else. While I could include a member function to allow me to sort with dates and times it is only asking me to sort by time (or a one day time planner)
jzilliam (40)
Hey I encountered another problem with processing the file specifically with the day? What's going on here?

Okay so my program is 99.999% done its just I need one single thing to work. I have this file called "agenda.txt" and I was wondering how to update the file whenever something is outstreamed to the file. For example:
./a.exe -ps

This should print the schedule like this (it did print like this just in a different file):
Fishing with Donald and Donald | 2021 | 1 | 29 | 8:14am | 115
Meeting with Bob | 2021 | 10 | 29 | 8:30am | 15

However whenever the Outstream is linked to the same file it erases everything

ofstream deletes everything in the file when it is opened. If you want to append to the end of the data, then you need to open in append mode (look it up).

However, isn't this operation what is required? Read in the file contents to the vector, change as required as per the command line argument(s) and then write the whole vector contents back to the file?

I looked it up however it is still quite confusing. Where would I place the outstream so the instream processes before the outstream.

Here's what I have:

At the end of main after all processing. Basically in pseudo code:

1

open input file and read all data
loop processing until all actions performed
open output file and write all data
