Well i read it in a source code of a program and have been banging my head to learn more.
Also can any one explain how to initialize random number generator, why should i ise srand() only.
I also have been reading c for (on and off) for a year or so, but i still dont understand codes of open source programs(i am in first year of under graduation does any thing have to do with that).
are there any websites that you suggest(apart from topcoder) that partial newbies can visit without becomming intimidated(by the full weight of complexity of prgramming,i still realise that thats the bitter truth).
