Yet I only find job postings where they're looking for someone to code C/C++. I still don't know what that means. Does that mean both or one or the other? Or that they're still undecided as to what language to use? Maybe they don't know what language they are using..?
Basically what this means is that you will compile all your code using a C++ compiler, but because C++ is backwards compatible with C, they just call it "C/C++".
A lot of developers still write in a C-esque fashion because that's what they were taught in school or just haven't learned a new way of doing things. Developers still use the C standard library for file IO instead of C++ fstream. Developers use new and delete with raw pointers and manage the memory themselves instead of using a vector. I was recently on a project where all the code was written in an old C style- variables declared at the top of each function, raw pointers everywhere, usage of C strings, etc. Memory leaks and segfaults were abundant. Uninitialized and unused variables a'plenty. And they were using a C++ compiler.
In my group's case, it means both. We expect new hires to know C++ for most of our work, but for portability across different architectures C is sometimes still necessary.
