  • 0

I am very used to Java where I can create an ArrayList to hold multiple objects, but I don’t know how to do it in C++.

I have 6 different objects:
WebcamData
UltrasonicData
KinectData
ImuData
GpsData
SickData

I need to hold an instance of each in one array.

In java it would be like:

ArrayList array = new ArrayList();
array.add(new WebcamData);
array.add(new UltrasonicData);

etc…

How can I make a similar array in C++?

Thank you

    Use std::vector<boost::any>:

    std::vector<boost::any> miscArray;
miscArray.push_back(Apple());
miscArray.push_back(Onion());
miscArray.push_back(Bear());
miscArray.push_back(Beer());

    Read the documentation:

    The implementation of boost::any is very simple, which means you can implement it yourself if you cannot use Boost library.
