and every approach and recommendations. alse let the code save the input data in a $.$txt file and load it when the program start again after being stopped and make a menu in main to choose what to do:

Create an employee Record Management system using linked list

that can perform the following operations:

$$ Insert employee record

$$ Delete employee record

$$ Update employee record

$$ Show details of an employee

$$ Search an employee

$$ Update the salary of an employee

The employee record should contain the following items

$$ Name of Employee

$$ ID of Employee

$$ First day of work

$$ Phone number of the employee

$$ Address of the employee

$$ Work hours

$$ Salary

Extra: Design a Graphical user interface for the employee Record

Management system

Approach:

With the basic knowledge of operations on Linked Lists like insertion, deletion of elements

in the Linked list, the employee record management system can be created. Below are the

functionalities explained that are to be implemented:

Check Record: It is a utility function of creating a record it checks before insertion

that the Record Already Exist or not. It uses the concept of checking for a Node with given

Data in a linked list.

Create Record: It is as simple as creating a new node in the Empty Linked list or

inserting a new node in a non$-$Empty linked list.

Smart Search Record: Search a Record is similar to searching for a key in the linked

list. Here in the employee record key is the ID number as a unique for every employee.

Delete Record: Delete Record is similar to deleting a key from a linked list. Here the

key is the ID number. Delete record is an integer returning function it returns $-1$ if no such

record with a given roll number is found otherwise it deletes the node with the given key

and returns $0.$

Show Record: It shows the record is similar to printing all the elements of the Linked

list.

Update salary: It add $2\%$ of the salary for every extra hour. By default, $32$ hours are

required for every employee.

Recommendations:

Although the implementation of exception handling is quite simple few things must

be taken into consideration before designing such a system:

$1.$ ID must be used as a key to distinguish between two different records, so while

inserting record check whether this record already exists in our database or not, if it already

exists then immediately report to the user an error message.

$2.$ The record should be inserted in sorted order, you can use the inserting node in

the sorted linked list seen in the lectures.
