I'm going to learn c++ for building sketches for arduino. Is there anything arduino doesn't use that I won't need to learn?

Question

the last program language that I learn was G.W. Basic 2.2

Answer 1

For Arduino sketches you might not need most features C++ has more than C (like classes, templates), pointers are rarely used as well.
Btw. if you want you can check out my latest project made for Arduino beginners that just hit beta status (so feedback would be appreciated)
