The company conducts multipleclinical trials concurrently. Each clinical trial is assigned a trial code together with description of theclinical trial, start date, end date, and the lead scientist. Each clinical trialinvolves at least one treatment, and each treatment belongs to only one trial.Treatment has its conduct date. When volunteers sign up for a treatment of a clinical trial, their contact detailsincluding full name, address, contact number, email address, as well as theirunique volunteer number are recorded. Each volunteer is involved in at leastone treatment, while each treatment is tested on at least 30 volunteers. In addition, medical details for each volunteer including weight, height, bloodtype, race, gender, and medical condition are also recorded separately.

- Question 1: Create a structure to specify data of employees in CS Department. The data to be stored is: Employee ID, Name, designation, Date of Joining and a flag to know whether the current employee is still in service or not. Assume maximum of 20 employees in the CS Department. Your program must be menu driven with following options: 1. Add a record (Employee ID, Name, Designation and Date of Joining of each employee) 2. Print the Employee ID, Name, Designation, Date of Joining and Status (whether the employed still in service or left) of each employee in tabular format. 3. Search specific employee. 4. Calculate total service of each employee.Student Database Management System We are making a project by means of data structure which will ensure the management of student’s record and profile. This is a simple student database management system developed in C++ by means of Data structure and Algorithms. It utilizes file handling and shows effective implementation of class and object of the programming language. This project will teach you how to add, list, modify and delete records in file.Following are the works which will be done in our project.1. Add Student Records:This feature allows you to add general information records. That includes the student’s name, course and section. All the added records in this student database management system are stored in file. (It may use different variety of nodes or a no linear data structure)2. Search Student Record:This feature allows you to search student records. All the added records in this student database management system are stored in file. (It may use…Delegation represents: a.
