Lying on resumes is very common, so is lying on job postings. It's a really weird arms race where no one is getting what they want.

I will say that I'm not surprised by this at all. I think a ton of people have been convinced that basically all languages are more or less the same, so they are confident putting languages they barely know on their resumes. "I know python and Java, how hard can C++ be?". This isn't a new problem, or even a "coding bootcamp problem"

I studied computer science at a small university in 2006, several of my friends went to a much larger university and studied Software Engineering

They didn't learn pointers back then either. They learned Uncle Bob Java and that was basically it.
