Can someone help to improve my programming knowledge?

Answer 1

Just check out "allitebooks.com" it has a tonne of material on whatever topic you're interested in...
Or just join "project euler" and test out your skills on various problems...

If you want something a bit more hardcore then download "the programming contest Manual" its got over 100 challenges that'll help you gain proficiency in whatever language you use...(those challenges are really something)..
