If you want a good understanding of the fundamentals etc, I cannot recommend CS50 enough. The original is more difficult and starts with basic stuff (you'll be asking the computer for individual pieces of memory etc)

There's also a python focused version, which is much easier. But this will make learning other languages in the future a bit more tricky. So, depends what you'd prefer.

Both are taught by David Malan, a Harvard professor who is easily one of the best lecturers I've seen.
Good luck!
Edit: Should've mentioned, they are all free or you can pay for a cert with edx.
