About Covid-19 Management System in C++

As previously stated, the Covid 19 Testing Management System is divided into three components, each with its own set of restrictions.

The Administrator Side is the system’s admin panel, where management can handle the system’s records.

To access the module’s features and capabilities, an admin credential is required in the Admin panel.

Individuals can register their details and plan their testing time slot on the User Module side of the system. This module typically holds static information about the application’s purpose and other details on the Public Website.

How the Covid-19 Management System Works (Architecture)

The system stores patient records, vaccination history, and confined-case data in a flat-file database (a single .dat file per record type). On startup, the program loads each file into memory, presents a menu, and writes any changes back to disk on exit. A simple, single-user model that runs on any Windows PC with a C++ compiler.

Core Data Structures

struct Patient {
    int patient_id;
    char name[60];
    int age;
    char gender;
    char address[100];
    char status[20];    // confirmed / suspected / recovered / deceased
    char admission_date[12];
};

struct Vaccination {
    int vacc_id;
    int patient_id;
    char vaccine_brand[40];
    char dose_type[10];     // 1st / 2nd / booster
    char date_given[12];
};

Notice the use of fixed-size char arrays instead of std::string. This is intentional for the file I/O step. A struct with fixed-size members can be written and read with a single fwrite() / fread() call, which keeps the code simple. If you switched to std::string, you would need a serialization step.

Sample Code: Adding a New Patient Record

#include <iostream>
#include <fstream>
#include <cstring>
using namespace std;

void addPatient() {
    Patient p;
    cout << "Patient ID: ";       cin >> p.patient_id;
    cout << "Name: ";             cin.ignore(); cin.getline(p.name, 60);
    cout << "Age: ";              cin >> p.age;
    cout << "Gender (M/F): ";     cin >> p.gender;
    cout << "Address: ";          cin.ignore(); cin.getline(p.address, 100);
    cout << "Status: ";           cin >> p.status;
    cout << "Admission Date (YYYY-MM-DD): ";  cin >> p.admission_date;

    ofstream out("patients.dat", ios::binary | ios::app);
    out.write(reinterpret_cast<char*>(&p), sizeof(Patient));
    out.close();

    cout << "Patient record saved.\n";
}

The ios::app flag opens the file in append mode, so each new patient is added to the end without overwriting existing records. The reinterpret_cast<char*> tells the compiler to treat the struct as a raw byte sequence for binary writing.

Sample Code: Listing All Patients

void listPatients() {
    ifstream in("patients.dat", ios::binary);
    if (!in) {
        cout << "No patient records found.\n";
        return;
    }

    Patient p;
    cout << "\nID    Name                          Age  Status\n";
    cout << "----------------------------------------------------\n";
    while (in.read(reinterpret_cast<char*>(&p), sizeof(Patient))) {
        cout << p.patient_id << "    "
             << p.name << "    "
             << p.age << "   "
             << p.status << "\n";
    }
    in.close();
}

The while (in.read(...)) loop continues until read() hits end-of-file and returns false. Each iteration loads exactly one Patient struct from the file.

Suggested Capstone Enhancements

Switch to MySQL for a more impressive capstone defense. File-based storage is fine for a starter project but examiners expect a real RDBMS.
Add a search-by-age-range feature. Useful for filtering high-risk groups (60+ or under 18).
Build a vaccination-status report that joins Patient and Vaccination data. Examiners love multi-entity reports.
Add data validation: reject negative ages, validate the date format, prevent duplicate patient IDs.
Integrate with a barcode scanner using a serial-port library. Real hospitals scan IDs at registration.

Common Mistakes Building This Project

Forgetting cin.ignore() before getline(). After reading an integer with cin >> age, the newline stays in the buffer and the next getline() reads an empty string.
Mixing text and binary I/O. If you write with ios::binary, you must read with ios::binary too. Mismatched modes corrupt records on Windows.
Hardcoding the file path. Use relative paths so the project runs from any folder. "patients.dat" works; "C:\\Users\\You\\..." only works on your machine.
Not handling the empty-file case. Run the program once with no .dat files yet and confirm it does not crash.
Forgetting to close files. The destructor closes them automatically, but explicit close() calls make the code clearer and easier to debug.

In Summary

As concerned individuals and aspiring information technology, we have been greatly affected by the adversity of the Corona Virus’s implications, and have thus decided to develop a solution that aims to create a digital tracking and monitoring system in order to alleviate the panic caused by the virus’s implications and severity.

This digital solution system is designed to assist the general public in obtaining all relevant and necessary information about the situation in order to keep them informed and updated, as well as to provide them with immediate and preliminary assistance if they develop COVID-19 virus symptoms so that they can receive immediate medical care and attention.

Thank you and Happy CODING!

Frequently Asked Questions

What features should a Covid-19 Management System include?

The core modules are: patient registration (basic demographics and admission status), vaccination tracking (which vaccine, dose number, date), case status (suspected, confirmed, recovered, deceased), search and filter, and reporting (daily case counts, vaccination rates). For a BSIT capstone, also add user login with role-based access (admin, encoder, viewer) to demonstrate authentication.

What database should I use for a C++ Covid management project?

For a starter version, flat-file binary storage with .dat files is the simplest. For a stronger capstone, integrate MySQL using the C++ Connector library. The MySQL version impresses panels more because it demonstrates SQL knowledge alongside C++.

How do I compile and run a C++ project in Dev-C++?

Open Dev-C++, click File → New → Project, choose “Console Application” and C++ as the language. Add your .cpp files via Project → Add to Project. Compile with F9, run with F10. If you get linker errors, make sure all .cpp files are listed in the project (not just open in tabs).

Can I use this project as my BSIT capstone?

Yes, with modifications. The file-based version is more of a “mini-project” by capstone standards. To make it capstone-worthy, switch to a real database (MySQL or SQLite), add user authentication, build a reporting module with charts, and write a full Chapter II Related Literature review of existing Covid management systems.

How do I handle date input in C++?

The simplest approach is storing the date as a char[12] string in “YYYY-MM-DD” format. Validate that the format matches before saving. For more advanced projects, use the <chrono> library (C++20+) or the older <ctime> header for proper date arithmetic. For a starter project, plain string storage is enough.
