Finance Tracker Using C++

By Abhishek Gupta

This program provides a simple and interactive way for users to record and manage their financial transactions.

This code represents a finance tracker application, facilitating users to manage their monetary transactions. 

Here’s a detailed explanation:

1. Header Files & Namespace:
- The program includes three headers: for input-output operations, for dynamic array handling, and for managing string data types.
- The line using namespace std; is a directive to use the standard namespace, which avoids the need to write std:: before standard library types and functions.

2. Transaction Struct:
- Defines the blueprint of a monetary transaction.
- Description: A string describing the transaction.
- amount: A double representing the monetary value of the transaction.
- date: A string denoting the date of the transaction.
- type: A string indicating whether the transaction is an "Income" or an "Expense".

3. Finance_track Class:

- Private Member:
- Transactions: A vector storing all the transactions of type Transaction.

- Public Methods:
- addTransaction(): Accepts a Transaction object by reference and adds it to the transactions vector.
- DisplayTransactions (): Iterates over the transactions vector, displaying details of each transaction to the console.
- getTotalBalance(): Calculates the total sum of amounts from all transactions in the transactions vector and returns it.

4. Main Function:
- An instance of the Finance_track class named tracker is created.
- A menu is repeatedly presented to the user offering four options: adding a transaction, displaying all transactions, viewing the total balance, and exiting the program.

- The user's menu choice is captured in the variable choice.

- The switch statement handles the user's choice:
1. Add Transaction:
- A temporary Transaction object named transaction is created.
The user is prompted to provide details of the transaction (description, amount, date, and type).
- cin. ignore() ensures any leftover newline characters from previous inputs are discarded, ensuring getline works correctly.
- The filled transaction object is passed to addTransaction() to add it to the transactions vector.
2. Display All Transactions:
- Calls displayTransactions() to show all recorded transactions.
3. Display Total Balance:
- Calls getTotalBalance() to calculate and display the total balance.
4. Exit:
- Prints an exit message and exits the loop.
- Any other number results in a message indicating an invalid choice.

 

5. Looping:
- The do-while loop keeps the program running, continuously displaying the menu until the user chooses to exit (by entering 4).

6. Program Termination:
- The program finishes by returning 0, which signifies successful completion.

Overall, this program provides a simple and interactive way for users to record and manage their financial transactions.
