I think someone said that I do plan to first learn C, and then learn C++. This is incorrect, I have no intentions to learn C++.
Almost all C++ tutorials I have seen do not assume that you already know C. Actually, most of them start with things that are almost done the same way in both C and C++. This gets more confusing as simple C code often is valid C++ code too.
The new scripting engine is probably going to be closer to C++ than C, which is not at all object oriented.
If you want to learn C++, I do not think you should start with C. Actually, if you want to start with either C or C++, you should rethink your plans
ESR explains that very well, in my opinion, and although this article itself is probably not what you want, the section I point at should be useful.
