Hi people, This semester I am going to be a tutor for a master course class on C++ in HEP... I would like to listen from people with more expertise on the field: 1. What do students find (in general) difficult to understand in C++ from your experience with teaching it? In my case I think the most difficult part in C++ was the use of references and pointers -at certain points I am still feeling uncomfortable with using them. So I am trying to refresh, even theoretically, the whole point of refs and pointers (having to do with memory treatments of the computer). What are the most common , you think, questions one might receive on the language? This could as well deserve to be in Academic Guidance, but I'm also aiming for CS experts. Nevertheless, mods feel free to move it if you find it necessary..
