This is a C++ project I made to practice object-oriented programming (OOP) and to build something a bit more complete. The program simulates a simple bank system where you can create accounts, deposit and withdraw money, transfer funds, and apply interest. I put extra effort into this one to really understand how to organize a bigger project.
- Create accounts with initial balances and interest rates.
- Perform deposits, withdrawals, and transfers (e.g., $2000 from "1010" to "1012").
- Track transaction histories using vectors.
- Apply interest to savings accounts (2% for #1010, 9% for #1012).
I made this project to get better at using classes, vectors, and OOP ideas in C++. I wanted to see if I could put together a small system that feels more like a real application, and learn how to manage more code and features.
- Make sure you have a C++ compiler (like g++) installed.
- Compile the code:
g++ src/mainBankAccount.cpp src/fns_BankAccount.cpp -I include -o bank - Run the program:
./bank
- Account #1010 created with balance: $5000.00, Interest rate: 2%
- Account #1012 created with balance: $3000.00, Interest rate: 9%
-
Deposit to #1010: $1000.00
-
New balance for #1010: $6000.00
-
Withdrawal from #1012: $500.00
-
New balance for #1012: $2500.00
-
Transfer from #1010 to #1012: $2000.00
-
New balance for #1010: $4000.00
-
New balance for #1012: $4500.00
-
Applying interest for #1010 (2%): $80.00 -New balance for #1010: $4080.00
-
Applying interest for #1012 (9%): $405.00 -New balance for #1012: $4905.00
- How to use classes and private data to keep things organized and safe.
- How to use vectors to store lists of transactions that can grow as needed.
- How to use inheritance and virtual methods for different types of accounts or actions.
- How to split code into different files and keep things tidy with
src/andinclude/folders. - How to build a project that feels more like a real-world application, not just a small example.
