Applications of std::Variant
Following are some main applications of the std::variant:
- Handling Multiple Data Types: One of the most common use cases for std::variant is when you need to work with functions or classes that can accept different data types. Instead of writing multiple overloads, you can use a variant to streamline your code and make it more maintainable.
- State Machines: State machines, a crucial concept in software engineering, often require managing different states and transitions. std::variant simplifies this by allowing you to represent states as types and transitions as functions, resulting in clean and efficient code.
std::variant in C++ 17
In the world of modern C++ programming, the std::variant is a powerful tool that allows you to work with multiple data types in a flexible and type-safe manner. In this article, we will discuss std::variant and explore its fundamentals, applications, and benefits with practical code examples.
Prerequisites: C++ data types, functions, unions, and classes.
