<P> Donald Knuth (1993, commenting on pre-standardized C++), who said of Edsger Dijkstra that "to think of programming in C + +" "would make him physically ill",: </P> <P> The problem that I have with them today is that...C++ is too complicated . At the moment, it's impossible for me to write portable code that I believe would work on lots of different systems, unless I avoid all exotic features . Whenever the C++ language designers had two competing ideas as to how they should solve some problem, they said "OK, we'll do them both". So the language is too baroque for my taste . </P> <P> Ken Thompson, who was a colleague of Stroustrup at Bell Labs, gives his assessment: </P> <P> It certainly has its good points . But by and large I think it's a bad language . It does a lot of things half well and it's just a garbage heap of ideas that are mutually exclusive . Everybody I know, whether it's personal or corporate, selects a subset and these subsets are different . So it's not a good language to transport an algorithm--to say, "I wrote it; here, take it ." It's way too big, way too complex . And it's obviously built by a committee . Stroustrup campaigned for years and years and years, way beyond any sort of technical contributions he made to the language, to get it adopted and used . And he sort of ran all the standards committees with a whip and a chair . And he said "no" to no one . He put every feature in that language that ever existed . It wasn't cleanly designed--it was just the union of everything that came along . And I think it suffered drastically from that . </P>
