Requirements

Application should run from the command line and should have the following features:

• Users can add an expense with a description and amount.
• Users can update an expense.
• Users can delete an expense.
• Users can view all expenses.
• Users can view a summary of all expenses.
• Users can view a summary of expenses for a specific month (of current year).

Here are some additional features that you can add to the application:

• Add expense categories and allow users to filter expenses by category.
• Allow users to set a budget for each month and show a warning when the user exceeds the budget.
• Allow users to export expenses to a CSV file.

$ expense-tracker add --description "Lunch" --amount 20
# Expense added successfully (ID: 1)

$ expense-tracker add --description "Dinner" --amount 10
# Expense added successfully (ID: 2)

$ expense-tracker list
# ID  Date       Description  Amount
# 1   2024-08-06  Lunch        $20
# 2   2024-08-06  Dinner       $10

$ expense-tracker summary
# Total expenses: $30

$ expense-tracker delete --id 2
# Expense deleted successfully

$ expense-tracker summary
# Total expenses: $20

$ expense-tracker summary --month 8
# Total expenses for August: $20

Implementation

You can implement the application using any programming language of your choice. Here are some suggestions:

• Use any programming language for any available module for parsing command arguments (e.g. python with the argparse , node.js with commander etc).
• Use a simple text file to store the expenses data. You can use JSON, CSV, or any other format to store the data.
• Add error handling to handle invalid inputs and edge cases (e.g. negative amounts, non-existent expense IDs, etc).
• Use functions to modularize the code and make it easier to test and maintain.
