C++ and Java, say, are presumably growing faster than plain C, but I bet C will still be around.
C++ is a pile of crap.
Now, it's my belief that Python is a lot easier than to teach to students programming and teach them C or C++ or Java at the same time because all the details of the languages are so much harder. Other scripting languages really don't work very well there either.
This evolution may compromise Java's claim of being simpler than C++, but my guess is that the effort will make Java a better language than it is today.
Java and C++ make you think that the new ideas are like the old ones. Java is the most distressing thing to hit computing since MS-DOS.
The central problem of C and C++ is that they require programmers to do their own memory management
C is declining somewhat in usage compared to C++, and maybe Java, but perhaps even more compared to higher-level scripting languages. It's still fairly strong for the basic system-type things.
I made up the term "object-oriented," and I can tell you I did not have C++ in mind.
Java is C++ without the guns, clubs and knives.
The Wesnoth devs are good but not exceptionally so, and we're weighed down by a crappy implementation language (C++). Nevertheless our productivity, in terms of goals achieved per hour of work, is quite high.
C++ is my favorite garbage collected language because it generates so little garbage
Web servers are written in C, and if they're not, they're written in Java or C++, which are C derivatives, or Python or Ruby, which are implemented in C.
C++ is in that inconvenient spot where it doesn't help make things simple enough to be truly usable for prototyping or simple GUI programming, and yet isn't the lean system programming language that C is that actively encourages you to use simple and direct constructs.
After all, C++ isn't a perfect match for Java's design aims either.
C++ is designed to allow you to express ideas, but if you don't have ideas or don't have any clue about how to express them, C++ doesn't offer much help.
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do it blows your whole leg off.
