A real-world example of template usage in C++

In the realm of financial software, handling various types of assets and currencies in a flexible, type-safe, and efficient manner is crucial. C++ templates offer a powerful mechanism to achieve this flexibility by allowing developers to write generic and reusable code that can operate with any data type.

Imagine developing a financial system that must handle multiple currencies such as USD and EUR, and manage various assets such as stocks or bonds. By using templates, we can define classes that operate generically on these types without duplicating code for each specific currency or asset type. This approach not only reduces redundancy but also enhances the system’s scalability and maintainability.

In the following sections, we will look at a detailed example of a financial system implemented using C++ templates. This example will show you how to define and manipulate prices in different currencies, how to create and manage...
