While i was searching for a good tutorials(after finishing the one on this site)...i found a site with links to lots of tutorials and it said that this is the best on the net...can u plz check out the exercises for every section because i tried to solve them but the strange thing is that in order to solve them you have to know further sections....for examples the first section in declarations there;s a questions that needs using if ....in the looping section....some examples need using arrays while the arrays section are explained after these exercises.
