1. How to Begin… ?

2. Start with… Clear your basics of C and Data Structures
Reference Books:
1. Head First C
2. The C Programming Language : Kernighan & Ritchie
3. Video Lectures : IIT Delhi
(available on DC)

3. Practice on Online Judges…
~ 20,000 questions available
Questions from various past contests
One of the best choices to start with.
Archive of many contests
Classified on the level of difficulty
Editorials of past questions

4. One of the oldest judges Well categorized questions.
One of the oldest judges
Well categorized questions.
Strict constraints on format of Output.
For queries:
To debug:
There is a plethora of online judges available.
What we suggest you, is to START with one of these. The REST you will discover yourself in due time.

5. Reference websites… www.cplusplus.com :
can help you with nearly everything C++ has to offer. :
algorithms of standard problems with code, but we suggest you to try implementing them by yourself. :
awesome tutorials

6. Verdicts, you may get… AC- Accepted, correct solution
WA- Wrong Answer, something wrong with logic
PE- Presentation Error, incorrect format of output (whitespaces)
TLE- Time Limit Exceeded, the time complexity needs to be reduced. Optimize your solution or try a better algorithm
CE- Compilation Error, code could not be compiled on the system.
Runtime Errors-
SIGSEGV-The program accessed memory incorrectly, exceeding environment limits.
SIGFPE- incorrect arithmetic operation, like divide by zero

7. Contests http://www.codechef.com/ Long challenges: 10 days
(work hard and you may get codechef T-shirts too)
Cook-Off: 2.5 hrs
Contests by various colleges

8.
2 hour contests
questions of varying difficulty
time penalty +wrong submissions penalty + hack
help to test and increase your speed and accuracy

9.
a great place to learn
very good questions
even better editorials
Its better to practice on online judges prior to it. When you are familiar with basics, go for it…

10. ACM-ICPC ( International collegiate programming contest)
Among the most prestigious programming contests
Aim for it from now
Yearly competition ( prelims, national, international level )
You get to compete against the finest programmers and learn a lot.
