I told someone today that C++ was now faster than C. He wasn't buying it. I challenged him to an optimization contest. I whipped up a C++ program to sort 2^31 randomly generated integers. It generates and sorts the integers in around 40 seconds on my machine.
I was evil, though I warned him that C++ now allows one to take advantage of modern hardware in ways that C does not. I used <thread>.
Technically, threading was added to the C standard in C11. But no compiler on Godbolt implements it.
