Inspiration
As a beginner in programming and C++, I wanted to build something practical that reflects a real-world use case. Billing systems are commonly used in shops and stores, so I chose to create a simple Invoice System that demonstrates how basic programming concepts can solve real problems.
What it does
INVOICE_SYSTEM is a console-based billing application that allows users to:
- Add items with price and quantity
- Automatically calculate the total bill
- Display a clean and structured bill summary
- Store bill details in a text file
How we built it
The project was built using:
- Language: C++
- Tools: VS Code, GitHub
- Concepts used:
- Functions
- Loops
- Conditional statements
- Basic file handling
The focus was on keeping the system simple, readable, and beginner-friendly.
Challenges we ran into
- Correctly calculating the total bill
- Managing user input without errors
- Structuring the program logic cleanly
- Understanding how to handle files in C++
Accomplishments that we're proud of
- Successfully built a complete working invoice system
- Implemented automatic bill calculation
- Created a clean console user interface
- Completed a real-world project as a beginner
What we learned
- How real-world billing systems work at a basic level
- Improved understanding of C++ fundamentals
- Better problem-solving and debugging skills
- Confidence in building practical projects
What's next for INVOICE_SYSTEM
- Add GST/tax calculation
- Improve bill formatting
- Add product database support
- Create a GUI-based version in the future
