This work is to implement an inter-urban transport network
I coded 12 methods with c++, it does not compile. There are errors. The 13th method is coded by the teacher please do not touch it. The methods are in the files Graph.cpp and Graph.h. I translated the comments of the methods in English in Graph.cpp. For this first part of work, I need it to compile so that I can do the second part of work that concerns the files networkInterurbain.cpp.
Can you fix the errors so that it compiles in Graphe.cpp s.v.p?
I drop all the files of the projet but for the moment I need help only in Graphe.cpp
Thanks
