The Languages
C++ is well-suited for large projects because it has an object-oriented
structure. People can collaborate on one program by breaking it up into
parts and having a small group or even one individual work on each part. The
object-oriented structure also allows code to be reused a lot, which can
cut down development time. C++ is also a fairly efficient language -
although many C programmers will disagree.
C is a popular language, especially in game programming, because it doesn't
have the extra packaging of the object-oriented C++. Programmers use C
because it makes programs slightly faster and smaller than programs written
in C++. You might wonder, however, whether it's worth giving up the
reusability of C++ to get the small increase in performance with C,
especially when C++ can, where necessary, be written in a C programming
style.
Pascal is primarily a teaching language. Few industrial programs are written
in Pascal. Pascal tends to use keywords instead of C-style braces and
symbols, so it is a bit easier for beginners to understand than languages
like C++. Still, not everyone thinks Pascal is just for the schools. Borland
, the huge compiler software company, has been pushing Delphi as an
industrial strength programming language. Delphi is an object-oriented
version of Pascal, and currently, only Borland compilers use it.
Fortran is a number-crunching program, and it is still used by scientists
because the language allows variables of any size up to the memory limit of
the machine. Fortran is especially convenient for engineers, who have to
mathematically model and compute values to high precision. Fortran, however,
isn't nearly as flexible as C or C++. Programming in Fortran is rigid, with
strict rules on whitespace and formatting, which sometimes makes reading
Fortran programs difficult.
Java is a multi-platform language that is especially useful in networking.
Of course, the most famous usage of Java is on the web, with Java applets,
but Java is also used to build cross-platform programs that stand alone.
Since it resembles C++ in syntax and structure, learning Java is usually
quite easy for most C++ programmers. Java offers the advantages provided by
object-oriented programming, such as reusability; on the other hand, it can
be difficult to write highly efficient code in Java, and Swing, its primary
user interface, is notoriously slow. Nevertheless, Java has increased in
speed in recent years, and version 1.5 offers some new features for making
programming easier.
Perl was originally a file management language for Unix, but it has become
well known for its use in CGI programming. CGI (Common Gateway Interface) is
a term for programs that web servers can execute to allow web pages
additional capabilities. Perl is great with regular expression pattern
matching, which is a method for searching text. Perl can be used for
databases and other useful server functions, and it is simple to pick up the
basics if you have experience in any imperative language. Web hosting
services prefer Perl over C++ as a CGI language because the web hosts can
inspect Perl script files, since they're just text files, while C++ is
compiled, so it can't be inspected for potentially dangerous code. Perl is,
however, notorious for its "write once" style of code -- it's very easy to
write Perl scripts taking advantage of lots of shortcuts that you later
cannot understand.
PHP is a common language for webpage design that is sometimes used as a
scripting language in *nix. PHP is designed for rapid website development,
and as a result contains features that make it easy to link to databases,
generate HTTP headers, and so forth. As a scripting language, it contains a
relatively simple set of basic components that allow the programmer to
quickly get up to speed, though it does have more sophisticated object-
oriented features.
LISP is functional language used mostly in computer science research. LISP
is unusual in that it stores (nearly) all data in lists, which are like
arrays, but without index numbers. The syntax for lists is very simple,
making it easy for programmers to implement complex structures.
Scheme A well-known variant of LISP, Scheme has a slightly simpler syntax
and not quite as many features. A common joke is that any large project
undertaken in Scheme will result in the reimplementation of most of LISP.
Nevertheless, Scheme is quite popular in academic circles and is the
introductory language of MIT's computer science department (and is taught as
part of Harvard's introductory sequence). Scheme's simplicity makes it a
good way to get started solving problems instead of worrying about
programming language syntax.
Of course, there are still many, many languages not discussed, a few major
ones being Prolog, Tcl, Python, COBOL, Smalltalk, and C#. Those are
generally related or similar to the programming languages I have described
above. The take home message is that different programming languages have
their advantages and disadvantages, and picking the appropriate language for
the task is often an important step in the process of developing an
application or program. | g*****g

knew it. C is not cool anymore but it still powers some of the
largest software projects including Linux Kernel.
Anyway, golden rule of engineering(or anything else in life): with
sufficient thrust, pigs fly just fine.

域里不值一提。
但在特定领域里的生态圈是dominant的,ME/EE的学生不会Matlab,在学校没法生存呀，
公司里到好一点,八仙过海，各显神通，会点Excel, pptx打遍天下的“高手”也是无处
不在：）

MS是哪年推出C#?
应该是2001/2002年以后了，那时Visual C++ 6.0 流行着。
