As a software engineer I think is best to have a Factory class so the system will be more light and clean organized.

The object of the class Money must be small as possible and withouthard ties with large memory chunks, so all configurations and external resources as configurations, json files, lists, etc, must be done by a Prototype Factory Singleton class: MoneyFactory.

A money object must be instantiated like:

static MoneyFactory * fr = MoneyFactory::instance();
const Money * bill = fr->money("USD",700.00);

The Money prototype will have a pointer to the MoneyFactory instance, so all convertions and transformations with money will be made by the Factory.

Money must rewrite some arithmetic operators: = + - / * < > == and >> for exchange:

const Money invoice = bill; // clone bill

invoice = bill * 3; // clone bill and multiply value by 3

invoice >> "BRL";   // exchange to Real

Steps

• 1. Create a test module ( 002-FactoryTest.cpp ) to verify each requirement

  • 1. Class existence and instantiation as Singleton
  • 1. Constructor parameters: config_file, signs_file, rates_file
  • 1.Class must get and set the parameters and controls to reload confs
  • 1. Methods: exchange

• 2. Implement the class MoneyiFactory

  • 1.class constructor, Singleton
  • 1.Prototype to clone, getters and setters
  • 1.Refactoring class Money to be thinner

user story:

• As a developer, I want a class Money with value, currency symbol, face value and the method exchange so that we can develop the finance app using it as a data type.

acceptance criteria:

• Properties:

  • value as integer,
    *currency symbol as String,
  • face value with currency symbol as String,
  • country as String,

• Methods:

  • Money::exchange("currency_symbol") returning a new Money object.

definition of Done:

When all tests PASS.

Notes

Must have a class Money implementing the properties: value as integer, currency symbol, face value with currency symbol as String, country and the method Money::exchange("currency_symbol") returning a new Money object.

• Create tests

• Document code

• Create class

As a finance student, I want to have a command to exchange money values so I can begin understanding how it works.

As a developer I want to have a study of financial recipes so I can create a financial framework of tools and utilities.
