To design an interactive program in C that maintains an employee database for a small office, we will use structures to store employee details. The program will have a menu-driven interface with options to create, read, modify, and delete employee records. The data for each employee will include attributes like Employee Name, Employee ID, Department Name, Salary, Position, and Date of Joining.

### Key Features:
- Creating a New Record: This option will allow the user to input details of a new employee and save the record.
- Reading/Listing of Records: This option will display a list of all employee records stored in the system.
- Modify the Record: This option will allow the user to modify details of an existing employee.
- Delete the Record: This option will allow the user to remove a particular employee’s record from the system.

### Program Logic:

We will use a structure to represent each employee, and then implement the following functionalities:

- Add a new employee to the database (add to a list).
- Display all employees.
- Modify the details of an employee by Employee ID.
- Delete an employee record based on Employee ID.

Below is the C code that implements these features:

```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define MAX_EMPLOYEES 100

// Structure to store employee details
struct Employee {
char name[50];
int emp_id;
char department[30];
float salary;
char position[30];
char date_of_joining[15];
};

// Function declarations
void create_record(struct Employee* employees, int* emp_count);
void list_records(struct Employee* employees, int emp_count);
void modify_record(struct Employee* employees, int emp_count);
void delete_record(struct Employee* employees, int* emp_count);
void display_employee(struct Employee emp);

int main() {
struct Employee employees[MAX_EMPLOYEES];
int emp_count = 0;
int choice;

while(1) {
// Displaying menu
