A Hospital Management System is software that facilitates its users some basic operations that take place in a typical hospital. This Hospital Management System in C language is a project for Hospitals having the following functionalities:

  • Printing Hospital Data
  • Print Patients Data
  • Sort by Bed Price
  • Sort by Available Beds
  • Sort by Name
  • Sort by Rating and Reviews
  • Print the Hospital's Name in a Specific City

All the functions will be operated through switch cases in the main function. There will be a menu for users for easy navigation.

Components of the Project

1. Structure for Hospital and Patients Data

The Structure for Hospital's and patient's data is defined below:

C 
// Structure for Hospital
struct Hospital {
    char name[50];
    char city[50];
    int beds;
    float price;
    float rating;
    int reviews;
};

//Structure for Patient
struct Patient {
    char name[50];
    int age;
};

2. Function to Print Hospital Data

This function prints all the hospital data.

C 
// Function to print hospital data
void printHospital(struct Hospital hosp) {
    printf("Hospital Name: %s\n", hosp.name);
    printf("City: %s\n", hosp.city);
    printf("Total Beds: %d\n", hosp.beds);
    printf("Price per Bed: $%.2f\n", hosp.price);
    printf("Rating: %.1f\n", hosp.rating);
    printf("Reviews: %d\n", hosp.reviews);
    printf("\n");
}

3. Function to Print all Patients Data

This Function prints all patient data.

C 
// Function to print patient data
void printPatient(struct Patient patient) {
    printf("Patient Name: %s\n", patient.name);
    printf("Age: %d\n", patient.age);
    printf("\n");
}

4. Function to Sort Hospitals by Bed's Price

This function sorts the bed prices of each hospital in ascending order.

C 
// Function to sort hospitals by beds price (ascending)
void sortByPrice(struct Hospital hospitals[], int n) {
    // Implement sorting logic: bubble sort
    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - i - 1; j++) {
            if (hospitals[j].price > hospitals[j + 1].price) {
                struct Hospital temp = hospitals[j];
                hospitals[j] = hospitals[j + 1];
                hospitals[j + 1] = temp;
            }
        }
    }
}

5. Function to Sort Hospitals by Available Beds

This function sorts hospitals by number of available beds in descending order.

C 
// Function to sort hospitals by available beds (descending)
void sortByBeds(struct Hospital hospitals[], int n) {
    // Implement sorting logic: bubble sort
    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - i - 1; j++) {
            if (hospitals[j].beds < hospitals[j + 1].beds) {
                struct Hospital temp = hospitals[j];
                hospitals[j] = hospitals[j + 1];
                hospitals[j + 1] = temp;
            }
        }
    }
}

6. Function to Sort Hospitals by Name

This function sorts hospitals by name in alphabetical order.

C 
// Function to sort hospitals by name (ascending)
void sortByName(struct Hospital hospitals[], int n) {
    // Using strcmp
    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - i - 1; j++) {
            if (strcmp(hospitals[j].name, hospitals[j + 1].name) > 0) {
                struct Hospital temp = hospitals[j];
                hospitals[j] = hospitals[j + 1];
                hospitals[j + 1] = temp;
            }
        }
    }
}

7. Function to Sort Hospitals by Rating and Reviews

This function sorts hospitals by number of reviews.

The logic used here is: If the hospital A's rating*reviews < Hospital B's rating*reviews then swap them.

C 
// Function to sort hospitals by rating and reviews (descending)
void sortByRating(struct Hospital hospitals[], int n) {
    // Based on Reviews
    for (int i = 0; i < n - 1; i++) {
        for (int j = 0; j < n - i - 1; j++) {
            if (hospitals[j].rating * hospitals[j].reviews < hospitals[j + 1].rating * hospitals[j + 1].reviews) {
                struct Hospital temp = hospitals[j];
                hospitals[j] = hospitals[j + 1];
                hospitals[j + 1] = temp;
            }
        }
    }
}

8. Function Print the Hospitals of any Specific City

This function takes input the name of city and returns the hospitals present in the specific city.

C 
// Function to print hospitals in a specific city
void printHospitalsInCity(struct Hospital hospitals[]) {
    char city[50];
    int hospitalsFound = 0;  

    printf("Enter city name (X, Y or Z): ");
    scanf("%s", city);

    printf("Hospitals in %s:\n", city);

    for (int i = 0; i < 5; i++) {
        // Use strcasecmp for case-insensitive comparison
        if (strcasecmp(hospitals[i].city, city) == 0) {
            printf("Hospital Name: %s\n", hospitals[i].name);
            printf("City: %s\n", hospitals[i].city);
            printf("Total Beds: %d\n", hospitals[i].beds);
            printf("Price per Bed: $%.2f\n", hospitals[i].price);
            printf("Rating: %.1f\n", hospitals[i].rating);
            printf("Reviews: %d\n", hospitals[i].reviews);
            printf("\n");
            hospitalsFound++;
        }
    }

    if (hospitalsFound == 0) {
        printf("No hospitals found in %s\n", city);
    }
}
