The aim of this post is to fight the generalized belief of C++ being too slow of a language for embedded environments. This belief goes around, saying that microcontrollers should still be programmed in C, or even in assembler. Probably you don't agree with me right now. The idea of C being much more efficient than C++ is so extended that it almost seems like sacrilege to debate it. That's why I'm about to make a series of comparisons between both languages, throwing in some real and objective numbers (code size, execution time, etc). After we prove that not only can C++ compete with good old C, we'll see it's actually a better alternative. For that, besides performance metric, I will compare things like safety, code readability or portability.
