I believe there’s no problems, you can go straight for C++.
Some points:
- C++ is superior to C (and more used);
- C++ was created to further expand upon C;
- And If you have learned C language first, it will be easier to learn C++ language!
But of course, and appy to all: both languages can be used in independent way, and also for different purposes. So the choice of whether you should learn (C, C++ or both) is up to you.
After learning you can compare and have your own conclusions - that will be about the same.
