Question: What are the five most important languages that programmers should know?
Bjarne Stroustrup: First of all, nobody should call themselves a professional if they only knew one language. And five is a good number for languages to know reasonably well. And then you’ll know a bunch, just because you’re interested because you’ve read about them because you’ve wrote a couple of little programs like [...]. But five isn’t a bad number. Some of them book between three and seven.
It would be nice beyond that to know something quite weird outside it just to have an experience, pick one of the functional languages, for instance, that’s good to keep your head spinning a bit when it needs to. I don’t have any favorites in that field. There’s enough of them. And, I don’t know, if you’re interested in high-performance numerical computation, you have to look at one of the languages there, but for most people that’s just esoteric.
