What language(s) should I learn to write web apps, iPhone apps, and websites?

I'm in the process of learning C++. But there's so much more that I want to do online - web apps, iphone apps, websites.

So I'm thinking of learning another language, one that would allow me to make (or at l开发者_如何学Goeast attempt to make) useful applications.

Now, what language should I look into learning? And, how do you recommend I go about learning it?

I'd guess Java wouldn't be a bad choise. You can use it for desktop applications, web applications, android applications.

c++ is a nice language for desktop applications.

Although in all honesty, learning a language is more about learning the logic/possibilities than the language itself. If you know C++ the jump to java/c# isn't too hard.

You can also use c# for desktop applications/web applications(asp.net backend).

Do take into account that iPhone applications use objective c.

As to to learning it. There are plenty of tutorials (and if you're interested in Android then the google site is a nice source). But one way of learning it that might be useful is just setting a goal for yourself and looking things up as you need them. This might cause you to review some things but it's a nice way to figure it out and try new things.

ANSI C first, then Objective C for Cocoa (iPhone, Mac), then C++. Never learn C++ first. Python is great for web development, as are a multitude of others. Get the basics first, start with C.

Some simple interpreted language would be good. Python, PHP, or Ruby for web development work. Python, Ruby, or Lua for applications development. Bash, or Lua for really short scripts and stuff. For stuff with a lot of text processing, Bash is king. Perl is (in my opinion) barely good for anything, but a lot of people like to use it for text processing and short little scripts as well.

Also, a good programmer is comfortable freely intermixing programming languages, so while you shouldn't be actively learning more than one at a time, it's good to know a few of them and know which ones are best for what use.

It really depends on what you want to do with it. For web development, I suggest Ruby. For desktop applications, try C++ or Python. It's whatever you choose.

If you're already learning C++, stick with that for now. When you master it, move on to another language.

.Net is a realy powerful technology! so on your place i would learn it as i language take c#

Win apps: winfroms + c#
Web apps/sites: asp.net(webforms. mvc) + c#
iphone apps: MonoTouch + C#
windows mobile: c#
Devices: .NET Micro Framework + c#

So Learn C#

I would suggest Java because as other people have said its not about learning a language but rather the principles. Java has good documentation, has been around a while and covers pretty much every concept behind programming (I hear pointers aren't the same as in C) If you go with another language you might get bogged down in the documentation and take away from the concepts that you are meant to learn from programming.

Once your a pro at Java you should pick up most other languages very quickly. You will also find that no matter what language you chose you will one day find yourself needing another one, if you don't have the concepts behind programming it won't be easy to learn
