CodeChef: A Platform for Aspiring Programmers
CodeChef was created as a platform to help programmers make it big in the world of algorithms, computer programming and programming contests. At CodeChef, we work hard to revive the geek in you by hosting a programming contest at the start of the month and another smaller programming challenge in the middle of the month.

Eligibility Criteria: Anyone with a knack for Programming :P
Our contests are open to all the programmers across the globe.
What's in it for you?
The idea behind these programming contests is that we want you to learn while competing. The dividing line may seem to be thin but it can be captured by the spirit of learning. If whatever you are doing is making you learn while you do so, we tend to believe that it is alright. However, all the participants are expected to abide to CodeChef Code Of Conduct.
Not just that, as a token of motivation we also give away goodies to the winners (only to school students) of the contest. You can know more about prizes here. However, our sole intention lies in making our users learn new concepts while competing.
