Blood Bank Management System (C++)

A console-based Blood Bank Management System developed in C++ using fundamental Data Structures. This project efficiently manages blood inventory, donor records, and patient requests.

---

Overview

This system simulates real-world blood bank operations by allowing users to manage donors, track blood units, process patient requests, and maintain issue history.

---

Data Structures Used

• Linked List → Blood Inventory Management
• Queue (FIFO) → Patient Requests Handling
• Binary Search Tree (BST) → Donor Records Management
• Stack (LIFO) → Blood Issue History & Undo Feature

---

Features

Blood Inventory

• Add blood units with date
• View complete inventory
• Search blood group
• Check low stock levels
• Remove expired blood (after 30 days)

Donor Management

• Add donor with eligibility check
• Delete donor by ID
• Search donor by ID
• Display all donors (sorted using BST)

Patient Requests

• Add patient request
• Process requests (FIFO order)
• View pending requests
• Cancel request

Blood Issue Tracking

• Store issued blood records
• View recent issues
• Count total issues
• Undo last issued record

---

Purpose

This project demonstrates practical implementation of core Data Structures in a real-world scenario:

• Linked Lists
• Queues
• Stacks
• Binary Search Trees

---

Technologies Used

• Language: C++
• Concepts: Data Structures & Algorithms (Linked List, Queue, Stack, BST)
• Compiler: Any standard C++ compiler (g++, Dev C++, CodeBlocks)
