Author side:
You may have noticed something missing here: no impressive of credentials. I
haven't been a professor at a Prestigious University for a quarter-century; neither am I a
top executive at a Silicon Valley giant. In some ways, I'm a student of Technology, just
like you are.
And my experience over the years has shown me that many of the people who
know the most about how technology works also have rather limited success in
explaining what they know in a way that will allow me to understand it. My interests,
and I believe my skills, lie not in being an expert, but an educator, in presenting
complex information in a form that is sensible, digestible and fun to read my books.
"What is real? How do you define real? If you're talking about what you can feel, what
you can smell, what you can taste and see, then real is simply, electrical signals
interpreted by your brain."
‘‘... I am just now beginning to discover the difficulty of expressing one’s ideas on
paper. As long as it consists solely of description it is pretty easy; but where reasoning
comes into play, to make a proper connection, a clearness & a moderate fluency, is to
me, as I have said, a difficulty of which I had no idea ...’’ – Harry

Essential C Programming Skills--Made Easy!
L
earn the all basics and advanced features of C programming in no time from
Bestselling Programming Author Harry. H. Chaudhary. This Book, starts with the
basics; I promise this book will make you 100% expert level champion of C
Programming.
Anyone can learn C Programming through this book at expert level.
Engineering Students and fresh developers can also use this book. In software
development section I explained live software project. As we all knows Author Harry
is basically known for his “Easy Techniques-Explanations in Programming World -
Learn with Fun Style !” To use this book does not require any previous
programming experience.
T
his book covers common core syllabus for BCA, MCA, B.TECH, M.TECH, BS
(CS), MS (CS), BSC-IT (CS), MSC-IT (CS), and Computer Science Professionals as
well as for Hackers. This book contains 1000+ Live C Program’s code examples, and
500+ Lab Exercise & 200+ Brain Wash Topic-wise Code book and 20+ Live software
Development Project’s. All what you need ! Isn’t it ?
T
his Book is very serious C Programming stuff: A complete introduction to C
Language. You'll learn everything from the fundamentals to advanced topics. If you've
read this book, you know what to expect a visually rich format designed for the way
your brain works. If you haven't, you're in for a treat. You'll see why people say it's
unlike any other C book you've ever read.
L
earning a new language is no easy. You might think the problem is your brain. It
seems to have a mind of its own, a mind that doesn't always want to take in the dry,
technical stuff you're forced to study.
T
he fact is your brain craves novelty. It's constantly searching, scanning, waiting for
something unusual to happen. After all, that's the way it was built to help you stay alive.
It takes all the routine, ordinary, dull stuff and filters it to the background so it won't
interfere with your brain's real work--recording things that matter. How does your brain
know what matters?

ntroduction-
Stuff you need to know about language levels –
Programming languages have different levels, depending on how much they
resemble human Languages. Programming languages that use common words and are
relatively easy for most folks to read and study are called high level languages. The
opposite of those are low-level languages, which are not easy to read or study.
High-level languages include the popular BASIC programming language as
well as other languages that just aren’t that popular any more BASIC reads almost like
English, and all its commands and instructions are English words — or at least English
words missing a few vowels or severely disobeying the laws of spelling.
The lowest of the low-level programming languages is machine language. That
language is the actual primitive grunts and groans of the microprocessor itself. Machine
language consists of numbers and codes that the microprocessor understands and
executes.
Therefore, no one really writes programs in machine language; rather, they use
assembly language, which is one step above the low-level machine language because
the grunts and groans are spelled out rather than entered as raw numbers.
Why would anyone use a low-level language when high-level languages exist?
Speed! Programs written in low-level languages run as fast as the computer can run
them, often many times faster than their high-level counterparts. Plus, the size of the
program is smaller.
A program written in Visual Basic may be 34K in size, but the same program
written in assembly language may be 896 bytes long. On the other hand, the time it takes
to develop an assembly language program is much longer than it would take to write the
same program in a higher-level language. It’s a trade-off.
The C programming language is considered a mid-level language. It has parts
that are low-level grunting and squawking, and also many high-level parts that read like
any sentence in a Michael Crichton novel, but with more character development.
In C, you get the best of the high-level programming languages and the speed of
development they offer and you also get the compact program size and speed of a low-
level language. That’s why C is so bitchen.
Note: No, I’m not being flip. C was developed at AT&T Bell Labs in the early 1970-
72s. At the time, Bell Labs had a programming language named B --B for Bell. The next
language they created was C - one up on B.
C is the offspring of both the B programming language and a language named
BCPL, which stood for Basic Combined Programming Language. But you have
to admit that the B story is cute enough by itself.
You would think that the next, better version of C would be called the D
language. But, no; it’s named C++.
C is considered a mid-level language. See the nearby sidebar, “Stuff you don’t
need to know about language levels,” for the boring details.
The guy who created the C programming language at Bell Labs is Dennis
Ritchie. I mention him in case you’re ever walking on the street and you happen
to bump into Mr. Ritchie. In that case, you can say “Hey, aren’t you Dennis
Ritchie, the guy who invented C?” And he’ll say “Why — why, yes I am.” And
you can say “Cool.”
