How to Store Objects of Differing Types in a C Container

Storing objects of varying types in a single C container can present a challenge, as standard containers like maps, vectors, and lists restrict members to a singular type.

One solution is to utilize Boost.Any, a type-safe wrapper that can contain instances of any type. By storing instances of Boost.Any in a container, you can accommodate objects of different types. This approach is preferred for its robustness and consideration of edge cases.

Alternatively, you can create a custom structure or union that contains members of all potential types, along with an indicator specifying the active type. However, unions require caution due to potential undefined behavior if the incorrect member is read, and they limit active members to one at a time.

It's worth noting that the C standard containers are already generic, but their members must be exclusively of the same type. The need for storing mixed-type objects is an intriguing problem, and it's important to carefully consider its applicability in your context.
