Re:Unless you can code a for loop (Score 1)

For example, I didn't hire the guy who said he can code C, C+, and C++.*

Actually C+ is a thing... at least according to Quantum Leaps, LLC:

"C+"—Object Oriented Programming in C
Warning: PDF download link: https://www.state-machine.com/...

From the C+ manual:

OOP in an object-oriented language is straightforward, because such a language natively supports the three fundamental meta-patterns. However, you can also implement these patterns in other languages, such as C, as sets of conventions and idioms. I call my set of such conventions and idioms “C+” [Samek 02]. The main objective of “C+” is to achieve performance and maintainability equivalent to the C++ object model. In fact, “C+” is, to a large degree, an explicit re-implementation of the C++ object model...

Stumbled across that a few days ago before reading here. Maybe your candidate thought "C+" on a resume would be provocative enough to trigger a discussion at interview?

P.S. Hello world, Slashdot! :)
