Banking Management System
Overview
Overview
A real-world C++ project that simulates banking operations, ideal for practicing file handling, OOP, and error validation.
Core Features
Create, update, and delete accounts
Deposit, withdraw, and transfer funds
Transaction history with timestamps
Secure login system
Mini Case Study
A student added encryption + unit tests to this project on GitHub and secured a fintech internship because it demonstrated strong understanding of real banking workflows.
Key Code Snippet
class BankAccount {
public:
string name;
int accountNumber;
double balance;
void deposit(double amount);
void withdraw(double amount);
};
Step 1 — Create Account Class
Use OOP principles.
class BankAccount {
public:
string name;
int accountNumber;
double balance;
void deposit(double amount);
void withdraw(double amount);
};
Step 2 — Build Menu-Based UI
Use switch-case for user actions.
Step 3 — Add File Storage
Store accounts in a .txt file or .dat file.
Step 4 — Add Validation & Error Handling
Prevent negative withdrawals
Validate account numbers
Common Mistakes
❌ No input validation
❌ Memory leaks due to raw pointers
❌ Not encrypting transaction logs
2. Inventory Management System
Overview
A perfect project for learning data structures like vectors, maps, linked lists, and sorting algorithms.
Features
Add/edit/delete products
Stock updates
Generate sales reports
Step-by-Step Tips
Use vector<Product> for fast iteration
Use sort() for price or quantity sorting
Add JSON-based data storage for advanced versions
Common Mistake
❌ Hardcoding product IDs instead of auto-incrementing them.
3. Online Chat Application (Networking Project)
Overview
A real-time chat app teaches client-server communication and multi-threading.
Key Features
One-to-one & group chat
Multi-client support
Message timestamps
Step-by-Step Tips
Use socket(), bind(), listen(), accept()
Use threads for handling multiple clients
Add encryption for professional-grade security
Mini Case Study
A GitHub user added SSL encryption using OpenSSL and got 300+ stars on the project.
4. Library Management System
Features
Manage books, borrowers, returns
Fine calculation
Search system (author, title, ID)
Tips
Use classes for Books, Users, and Transactions
Store data in files or SQLite
5. E-commerce Console Application
Features
Product catalog
Shopping cart
Checkout + order history
Common Mistake
❌ Not separating UI and business logic (bad OOP).
6. Tic-Tac-Toe AI Using Minimax Algorithm
Overview
Teaches recursion, game trees, and AI logic.
Highlights
Unbeatable AI
Score history
Option for GUI via SDL or SFML
Common Mistake
❌ Incorrect evaluation function leads to weak AI.
7. File Encryption & Decryption Tool
Techniques
XOR, Caesar Cipher, AES
Password protection
Secure file handling
Example
Implement simple XOR:
char encrypted = character ^ key;
8. Payroll Management System
Features
Salary calculation
Bonus & overtime logic
Payslip generation
Common Mistake
❌ Not handling date/time formatting correctly.
9. Weather Forecast Application
Features
API integration
JSON parsing
Temperature and humidity display
Best Practice
Use libcurl for API requests.
10. College Management System
Includes
Students
Teachers
Course registration
Attendance & grading system
Case Study
A student added a GUI and received excellent reviews during interviews.
