Question

Why is there no C language in sololearn?

Answer 1

Because we have C++, which is backwards compatible and covers most of the aspects you need to know in order to understand C programming language, i.e. if you have no problem understanding C++, you'll have no problem understanding C and porting codes from C to C++.

Answer 2

Well @Hasty thank you for answering my doubt ,I totally understand your point .
Its just that the way i have learned programming is first C then Cpp . So i think it would be more convenient if sololearn could add C language also.
