I never heard anyone say that C++ is a superset of C. Sure, the first version was a preprocessor on top of C and certainly that is common knowledge. But a superset? Never heard it. ObjC on the other hand...

You evidently haven't been looking at the stackoverflow questions coming in at the [c] and [c++] tags... ;) A frightening amount of [c][c++] tagging is expunged there every day.

Which is often just meaningless pedanticism. There are a lot of questions about C APIs where it's irrelevant whether the answer uses C or C++. The latter might not be an exact superset, but in most cases it's easily close enough.

Nearly everything that is mentioned in this blog is a subject of change / addition to the latest C standard, code named C2x. They are in discussions to introduce the following in C: * nullptr * auto * __has_include * make false and true first-class language features * constexpr and lots of other goodies [1]. https://gustedt.wordpress.com/2018/11/12/c2x/

Are they trying to make C literally become the same as C++ except classes and templates?

Are classes and templates not the bulwark of what makes C++ C++ though

The C++ specification has an entire appendix devoting to listing incompatibilities with C. Some features missing from this list: * A char literal is an expression of type int in C, but type char in C++. * String literals are const in C++ but non-const in C (although attempts to modify them are undefined behavior). * This program is legal C but not C++: int i; int i; * structs and unions occupy a different name space…

Well, they are trying to slim down, so to speak, the gap between C and C++ for the sake of a safer interoperability between the languages and for the sake of safer and secure code.

If C could fix _Generic from C11 and make it behave more like a lightweight version of templates, then I could say we have a huge potential of having a safer version of what we currently have.

That pink background to the left weighs 6 MB. Do you really think it's necessary?

I should probably make it smaller! 6MB is pretty indulgent. But I do like how it looks and this is mostly just a fun blog for myself :)

I think your blog looks great. The color palette you are using for text is very pleasing.

You are also contributing to global warming. It takes a energy to transfer this data all over the world. And poor people will will run out of their monthly phone data limit.

I've converted it to jpg and it's now 448K :)
