...Yourself C in 24 Hours Previous | Table of Contents | Next Hour 1 - Getting Started A journey of a thousand miles is started by taking the first step. —Chinese proverb High thoughts must have high language. —Aristophanes Welcome to Teach Yourself C in 24 Hours. In this first lesson you'll learn the following: What C is Why you need to learn C The ANSI standard Hardware and software required in order to run the C program What Is C? C is a programming language. The C language was first developed in 1972 by Dennis Ritchie at AT&T Bell Labs. Ritchie called his newly developed language C simply because there was a B programming language already. (As a matter of fact, the B language led to the development of C.) C is a high-level programming language. In fact, C is one of the most popular general-purpose programming languages. In the computer world, the further a programming language is from the computer architecture, the higher the language's level. You can imagine that the lowest-level languages are machine languages that computers understand directly. The high-level programming languages, on the other hand, are closer to our human languages. (See Figure 1.1.) Figure 1.1. The language spectrum. High-level programming languages, including C, have the following advantages: Readability: Programs are easy to read. Maintainability: Programs are easy to maintain. Portability: Programs are easy to port across different computer platforms. The C language's...

...C PROGRAMMING Section 1. Topics: Functions Statements Input Output Variables Introduction The C programming language has been the most popular high level language used for engineering applications for the last 20 years. It shares many common structures with other procedural languages, such as Pascal, and can be used for general purpose programming of a PC. However, it is also particularly good for development of embedded application programs such as those found in phones, video recorders and so forth. The term procedural language refers to the fact that the language uses procedures to do particular tasks such as printing on the screen. In C these procedures are known as functions and are described below. What is so good about a language like C? The basic reason such languages were developed was to make it easier for humans to program computers. The alternative is the language of the computer, i.e., binary codes. Clearly such ‘low-level’ languages are not very appealing for humans, although sometimes necessary for detailed engineering work. (In fact C is often ‘mixed’ with such languages for engineering applications.) C uses words and symbols that are part of, or similar to, normal language. This makes it easier for programmers to develop code. The C code is converted to the machine code by a special program called a compiler. See note 1. But perhaps the most useful thing about such a language is that it provides the developer with a library of ‘mini-programs’...

Preface to the Fifth Edition 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...

Looks like using ideone.com after it has successfully run Hello, World C code #include <stdio.h> int main(void) { printf("Hello, World!"); return 0; } Learning Exercises for you to try: 1. Remove the semi-colon (;) at the end of this statement: printf("Hello, World!"); main.c: In function ‘main’: main.c:5:4: error: expected ‘;’ before ‘return’ return 0; ^ 2.

...that you save any code you write. Also make sure you save any results or notes that you observe about your work. Note that you are unlikely to complete this worksheet in just one laboratory session. 2 Preliminaries Create a project in Eclipse called CS1002_Lab5 and create a corresponding class (say CS1002_Lab5). Try and organise your work (from the following exercises) into separate methods as we did in the previous worksheet. 3 Strings Copy the following code into your project and run the program. public static void main(String args[]) { double number = 1.0/3.0; System.out.println(number); DecimalFormat number_format = new DecimalFormat("#.##"); String formatted_string = number_format.format(number); System.out.println(formatted_string); } Is it showing you an error? Can you fix it? The DecimalFormat class enables us to format numbers (and other classes) in a variety of ways. In the above example we are formatting the number to two decimal places. Read up on this class in the JavaDocs as we will need it later. http://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html To complete the following exercise you will also need a good understanding of the String class: http://docs.oracle.com/javase/6/docs/api/java/lang/String.html http://docs.oracle.com/javase/tutorial/java/data/strings.html...

...Software from Source Code Objectives After reading this chapter and completing the exercises, you will be able to: * Understand basic elements of C programming * Debug C programs * Create, compile, and test C programs Text Reference: Chapter 10 – Developing UNIX/Linux Applications in C and C++ Programming Overview A computer program is a list of instructions given to a computer to make it perform a specific task or series of tasks. A programmer communicates these instructions to the computer in a language the computer understands. Computers, however, can only operate using binary code (1’s and 0’s), which makes a computer’s language very difficult for humans to understand. The solution to this problem is to create an intermediate language that both humans and computers can understand. These are called programming languages. Programmers create a list of instructions for the computer in a programming language such as C, C++, or Java. The C Programming Language The C programming language was released in 1973. C was created by Brian Kernighan, Dennis Ritchie and Ken Thompson working at Bell Labs. Both the UNIX and Linux operating systems are written in C. The C programming language is a high-level language because the code itself is written in relatively English-like statements. In 1978, Kernighan and Ritchie wrote "The C Programming Language," still one of the best C programming books available. The list of programming instructions is known as source...
