Clinic Management System in C++ | Codewithrandom
Introduction
Hello, learners. I hope you are all doing well. If you have been following us for a while, We hope that you are following our C++ projects. Today we will make a clinic management system using simple C++ concepts. I will be explaining the code if there is any hard part.
This project is beginner-friendly. Anyone who knows the overview of concepts like structures and linked lists can understand it easily.
If you are not familiar with the linked list concept, I will explain it in the coming sections.
User Interface and Working
The starting User Interface Image is seen above the Introduction section.
Let’s discuss each option in detail.
1)Adding patients record:
The first thing to do in a clinic management system is to have data about the patients. So we will use this option where we add the following information.
- Patient’s ID
- Patient’s First Name
- Patient’s Last Name
- patient’s Age
- Patient’s Gender
- Patient’s Blood Group
- Patient’s Contact
- Patient’s CNIC(National Level ID)
- Patient’s Address
These are just the necessary things to be taken from a patient before the doctor’s visit.
2)Adding the Patient’s prescription:
Once the patient is at the doctor, we need a way to take the patient’s input about the symptoms and diagnose them.
We should also provide more information like the tablets to be used.
(NOTE: Enter multiple things using a comma as a separation.)
3)Full History of a Patient:
If we want to view the history of a patient, we will use the patient’s ID assigned by us to display it.

We will display the information we took in the first and second options combined.

4)Delete Patient Record:
In general, the clinic should have a record of basic information, to use the next time.

But, we provide an option to delete a record if needed.

It is to learn the concept that we use in the project.
5) Update Patient Record
In case the patient’s details need to be changed, instead of deleting we can use this option.
It includes the contact numbers, addresses, medicines, symptoms.
In our project, we give the user the advantage of editing only the needed field instead of re-writing the whole information.
That is the explanation User Interface of the app and its functions.
Now let’s see the concepts we have to know to understand them clearly.
Concepts Used
- Structures
- Linked lists
- Classes and objects
1) Structures :
In C++ are user-defined data types, used to store a group of items of non-similar data types.
We will use it to create variables that can be used when we need them.
2)Linked Lists:
A linked list is a linear data structure in which the elements aren’t stored at contiguous memory locations. The elements in a linked list are linked using pointers.
3)Classes and Objects.
Classes in any language follow the OOP’s concepts such as abstraction, encapsulation, security, etc. So, we use objects to access the variables and methods inside a class. Objects are the instance of a class.

Code Explanation
Let’s start from the top.
After the headers, we create a structure called a “node”. Inside the structure, some variables and pointers are of the type node.
As I said before, we will use the linked list concept where each node will have the attributes declared inside the structure.
After the creation of pointers to the linked list, we create a class “doctor” that has the methods(functions) of the project.
Let’s explore each function.
1) void add()
In the add function, we create a new node to the linked list using the “new” keyword of C++.
Then we use the arrow symbol to assign the values to the attributes of that node.
It goes on every time we enter a new record.
We take the data that I have said in the explanation of the UI.
2)void show()
We use this function when the user selects the third option, Full History of the patient.
In this function, we assign the current and prev node as NULL. After that, we iterate through all the ids of the nodes till we find the ID of the patient required is found to display it.
3)void diagnosis()
We use this function when the user selects the option, Add patient prescription.
It is similar to add() function. Except, here we use the ID to first search the record of the patient and iterate till we find it.
Once found, we take the information that we need for the prescription.
4)void deletelist()
So, when we want to delete the record of a patient, we are deleting the node of a linked list using the ID.
So, we iterate through the nodes and when we find it, we delete it.
The linked list has a process for deletion.
If the node to be deleted is the starting one, we just simply make the next node as the start node.
If it is in middle, we use a temporary node to store and then delete it.
5) void update_data()
In this function, we just call the update_menu() and choose a value for the corresponding field.
Then using an if-else loop, we update only that field or the attribute of the chosen ID’s node.
6) void menu(), void dis()
These are just helper functions to display the options.
These functions are called in main() function.
7)main()
Here, we create an object to doctor and use the “.” operator to access the methods of class for the appropriate option.
Conclusion
We have reached the end of the article but we have a lot more projects in C++ coming.
