Let Us C

Abstract

It is mid 2004. World has left behind the DOTCOM bust, 9/11 tragedy, the economic downturn, etc. and moved on. Countless Indians have relentlessly worked for close to two decades to successfully establish ―India‖ as a software brand. At times I take secret pleasure in seeing that a book that I have been part of, has contributed in its own little way in shaping so many budding careers that have made the ―India‖ brand acceptable. Computing and the way people use C for doing it keeps changing as years go by. So overwhelming has been the response to all the previous editions of ―Let Us C‖ that I have now decided that each year I would come up with a new edition of it so that I can keep the readers abreast with the way C is being used at that point in time. There are two phases in every C programmer‘s life. In the first phase he is a learner trying to understand the language elements and their nuances. At this stage he wants a simple learning environment that helps him to master the language. In my opinion, even today there isn‘t any learning environment that can beat Turbo C/C++ for simplicity. Hence the first fifteen chapters are written keeping this environment in mind, though a majority of these programs in these chapters would work with any C compiler.
