Phonebook Management System in C Micro Project

Phonebook Management System in C

Welcome to this tutorial on building a phonebook management system using the C programming language. In this project, we will create a program that allows users to add contacts, search for contacts, and display all contacts in the phonebook. Let's get started!

The Code

      
#include 
#include 
#include 

#define MAX_CONTACTS 100

struct Contact {
    char name[100];
    char phone[15];
};

struct Contact contacts[MAX_CONTACTS];
int contactCount = 0;

void addContact() {
    if (contactCount >= MAX_CONTACTS) {
        printf("Phonebook is full. Cannot add more contacts.\n");
        return;
    }

    struct Contact newContact;

    printf("Enter Name: ");
    scanf(" %[^\n]s", newContact.name);

    printf("Enter Phone Number: ");
    scanf(" %[^\n]s", newContact.phone);

    contacts[contactCount++] = newContact;

    printf("Contact added successfully.\n");
}

void searchContact() {
    char searchName[100];
    printf("Enter Name to search: ");
    scanf(" %[^\n]s", searchName);

    int found = 0;

    for (int i = 0; i < contactCount; i++) {
        if (strcmp(contacts[i].name, searchName) == 0) {
            printf("Contact found:\n");
            printf("Name: %s\n", contacts[i].name);
            printf("Phone: %s\n", contacts[i].phone);
            found = 1;
            break;
        }
    }

    if (!found) {
        printf("Contact not found.\n");
    }
}

void displayContacts() {
    if (contactCount == 0) {
        printf("Phonebook is empty.\n");
        return;
    }

    printf("Contacts in the Phonebook:\n");

    for (int i = 0; i < contactCount; i++) {
        printf("Name: %s\n", contacts[i].name);
        printf("Phone: %s\n", contacts[i].phone);
        printf("---------------------------\n");
    }
}

int main() {
    int choice;

    while (1) {
        printf("\n----- Phonebook Management System -----\n");
        printf("1. Add Contact\n");
        printf("2. Search Contact\n");
        printf("3. Display Contacts\n");
        printf("4. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                addContact();
                break;
            case 2:
                searchContact();
                break;
            case 3:
                displayContacts();
                break;
            case 4:
                printf("Exiting...\n");
                exit(0);
            default:
                printf("Invalid choice. Please try again.\n");
        }
    }

    return 0;
}

Running the Program

1. Open a C compiler or IDE of your choice.
2. Create a new project and add the provided code.
3. Build and run the program.
4. You can now interact with the phonebook management system through the console interface.

Conclusion

Congratulations! You have successfully implemented a phonebook management system in C. This project provides a solid foundation for managing contacts and can be further expanded with additional features like contact deletion, modification, sorting, or saving contacts to a file for persistent storage.

I hope you found this tutorial helpful. Happy coding!
