  What is the best language in which to code your next project? If you are an embedded-system designer, that question has always been a bit silly. You will use, C—or if you are trying to impress management, C disguised as C++. Perhaps a few critical code fragments will be written in assembly language. But according to a recent study by the Barr Group, over 95 percent of embedded-system code today is written in C or C++.
