When looking for a language to program, don't focus on what's "cool" or useful as a career programmer. Focus on programming something you can run.
If you start using C++ because you heard it was the things that industry uses, etc you make find that you spend a lot of time trying to figure things out that might otherwise be achieved in an easier language such as C, Javascript or Basic.
Once you have successfully run something you will change little things and hopefully understand what you have made. Also, DO NOT FEEL BAD STEALING OTHER PEOPLES SOURCE CODE! This is how you learn, by taking source, modifying it one parameter at a time and then cobbling multiple pieces of source code together. You will learn much faster this way rather than trying to read developer documentation (which can be very daunting for a newcomer).
I would recommend downloading some some source and start tweaking. The language does not necessarily need to be one that I recommended. However I would recommend starting with Java and it is quite easy to learn.
PS: Try not to listen to the people who say that 'X' language teaches you bad programming skills. It's very easy to adapt yourself to new languages and everyone writes bad code starting out. You cannot avoid it, you are going to write bad code so live with it. The more important thing is not getting overwhelmed on the first try. If you do get overwhelmed you will most likely not try again for a long time. Java has its problems but guess what so does C++/C#/Ruby/Python/Objective-C/Visual Basic/etc. I recommend Java because it is EASY. Even a monkey could code in Java. It's also powerful enough that you can learn a bit. Later you can move to C++/Ruby etc.
Here's Hello world in Java:
class HelloWorldApp
{
public static void main(String[] args)
{
System.out.println("Hello World!"); // Display the string.
}
}
Get a compiler to run this code like Netbeans or Eclipse.
The next step is to do some tutorials like the ones that Sun have on their website
Making yourself valuable to employers depends on the job. SQL developers are valuable as are C# developers. Learning C# or Java is not a bad thing I would recommend knowing these. However knowing Frameworks i suppose is also valuable. Learn the frameworks for your avenue of interest: ie DirectX/OpenGL for game programmers, Cocoa for Mac developer and C#/.net for business programming.
Good luck coding :D
