The given code defines a virtual function in C++ with the name ChangeTrack. Here's what it does:

1. Virtual function: The virtual keyword indicates that this method is intended to be overridden in derived classes of the class where it's defined. It allows for behavior to change based on the specific subclass instance being used (polymorphism).

2. Function definition: The method ChangeTrack takes two parameters:

   • int side: Represents one piece of information, presumably about the "side" related to the track being changed.
   • int new_track: Represents another piece of information, likely the identifier or index of the new track to switch to.

3. Return type: The return type is void, meaning this function does not return any value.

4. Purpose: Based on the name and parameters, ChangeTrack likely performs an operation related to switching or changing the "track" (concept could depend on context, such as audio tracks, racing tracks, or some state of an object) to a new one (new_track), potentially considering a side variable.

In summary, this code declares a base-class virtual function that will allow derived classes to define the behavior for changing or switching tracks, potentially varying by context. The actual functionality will depend on the implementation provided by the derived class.
