Websites to test your programming skills

Dhimant

What you do once you have learned the basics of a new programming language ? Obviously you would want to test your skills ( Self evaluation ). There are few ways to test your ability to program , You could try to solve the programs given in the reference book or come up with a little project of your own. Either way it will help you improve your skills.

But if you would like to know how good you are at programming ( irrespective of the programming language ) compared to other programmers then you should examine one of the following Programming contest sites.
