Chapter 1: Introduction to C Programming Language Like anything new when you set out to do programming, you find yourself surrounded with strange and potentially weird terms, and fancied jargon. In this book, we’ll review those terms as well as present an overviewoftheentireprogrammingprocess.Itisverylikelythatyou’reeagertogetstartedwithwriting codes, and you may have already viewed a later chapter in this book. It is important to know a few key terms and programming concepts. History of C Programming Language Back in 1972, a computer scientist at AT&T’s Bell Laboratories started to develop some programs he neededforhisownuse.WhatDennisRitchiestarteddevelopingthenhasevolvedintotheCprogramming language, which by now is widely used around the world. He was trying to make computing as simple as possible. Dennis Ritchie realized that the then-current assembly language were much too complex. They attempted to reverse this trend by building a small, simple programming language on a minic
Chap-1 Number system 2076/12/19 v The way of represent a number in a computer system is called Number system. v Types of Number system are: 1. Binary number system 2. Decimal number system (dinary) 3. Octal number system 4. Hexadecimal number system A. The number system which contain two different digits (0,1)is called Binary number system. B. The number system which contain 10 different digits(0,1,2,3,4,5,6,7,8,9) is called Decimal number system(dinary). C. The number system which contain 8 different digits (0,1,2,3,4,5,6,7) is called Octal number system. D. The number system which contain 16 different digits (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F) is called Hexadecimal number system.
