contact_number_management_system

Aim:

To build a phone management system.

Objective of the Project:

To implement various operations associated with a contact book using data structures and file handling operations such as:

1. Inserting a contact
2. Displaying all contacts
3. Searching for a contact
4. Deleting a contact
5. Modifying a contact
6. Saving all the contacts to a file
7. Exit

Introduction:

A contact book contains the data a person needs when contacting his/her friends. The data may consist of various attributes such as first name, last name, number etc. What is crucial is that the data should be stored using appropriate data structures to perform relevant operations on it. Since operations such as insertion, deletion and modification need to be frequently performed on the contacts, a dynamically linked list is an apt choice to implement the contact book. This allows an effective utilization of memory and also makes insertion and deletion easier. Further, the contacts stored in the linked list need to be saved to a data file from time to time, so that a copy of the contact book exists even when the program terminates. For faster execution, we choose the format of the file to be binary (.dat), since no character translations need to be done when storing to and reading from a binary file. Language used: C++

Scope:

In future one change can be done by adding fingerprints of the persons of which the address is entered and one more major change which can be done in this project is that the snap of the person can be added.

Data structure used:

Since operations such as insertion, deletion and modification need to be frequently performed on the contacts, a dynamically linked list is an apt choice to implement the contact book. This allows an effective utilization of memory and also makes insertion and deletion easier. Further, the contacts stored in the linked list need to be saved to a data file from time to time, so that a copy of the contact book exists even when the program terminates. For faster execution, we choose the format of the file to be binary (.dat), since no character translations need to be done when storing to and reading from a binary file.

Framework:

When the program is run, it asks the user to enter the choice .The insert button gets input from the user and saves it temporarily. When the display option is chosen, the details are displayed to the user. The edit option is used to edit the details of the user based on the first name, date of birth and phone number. The delete option gets the name of the user and deletes the particular node. The save option save the details in an external DAT file.

Final result:

Conclusion:

Thus, the project to create a contact book and execute various operations on it has been successfully made. It can be used in electronic gadgets to save contacts in phone.
