Hi, I am a beginner in C++ so I hope you can be patient on me since my purpose is to learn.

I am now involved in a relatively complicated Data Analysis exercise.

I have a series of frames (vehicle data: trajectory) and I need to extract from them given informations.

For that, I put the info of each frame in a struct.
And I want to store the structs into a first vector grouped based on 1 info: time...
