Hello World Example

Hello World Example

 A C program basically consists of the following parts:

  Preprocessor Commands  Functions

  Variables  Statements & Expressions

  Comments Let us look at a simple code that would print the words "Hello World": #include int main() { /* my first program in C */ printf("Hello, World! \n"); return 0; } Let us take a look at the various parts of the above program:

 1. The first line of the program #include is a preprocessor command, which tells a C compiler to include stdio.h file before going to actual compilation

. 2. The next line int main() is the main function where the program execution begins.
3. The next line /*...*/ will be ignored by the compiler and it has been put to add additional comments in the program. So such lines are called comments in the program.
 4. The next line printf(...) is another function available in C which causes the message "Hello, World!" to be displayed on the screen.
 5. The next line return 0; terminates the main() function and returns the value 0.

Installation on Windows

Installation on Windows

 To install GCC on Windows, you need to install MinGW

. To install MinGW, go to the MinGW homepage, www.mingw.org, and follow the link to the MinGW download page

. Download the latest version of the MinGW installation program, which should be named MinGW- .exe

. While installing MinGW, at a minimum, you must install gcc-core, gcc-g++, binutils, and the MinGW runtime, but you may wish to install more

. Add the bin subdirectory of your MinGW installation to your PATH environment variable, so that you can specify these tools on the command line by their simple names

. After the installation is complete, you will be able to run gcc, g++, ar, ranlib, dlltool, and several other GNU tools from the Windows command line.

Installation on Mac OS

Installation on Mac OS

Installation on Mac OS If you use Mac OS X, the easiest way to obtain GCC is to download the Xcode development environment from Apple's web site and follow the simple installation instructions. Once you have Xcode setup, you will be able to use GNU compiler for C/C++. Xcode is currently available at developer.apple.com/technologies/tools/.

Installation on UNIX/Linux

Installation on UNIX/Linux

 If you are using Linux or UNIX, then check whether GCC is installed on your system by entering the

 following command from the command line: $ gcc -v If you have GNU compiler installed on your 

machine, then it should print a message as follows: Using built-in specs. Target: i386-redhat-linux 

 Configured with: ../configure --prefix=/usr ....... Thread model: posix gcc version 4.1.2 20080704 

(Red Hat 4.1.2-46) If GCC is not installed, then you will have to install it yourself using the detailed 

instructions available at http://gcc.gnu.org/install/. This tutorial has been written based on Linux and 

all the given examples have been compiled on the Cent OS flavor of the Linux system.

The C Compiler

The C Compiler

The source code written in source file is the human readable source for your program. It needs to be "compiled" into machine language so that your CPU can actually execute the program as per the instructions given. The compiler compiles the source codes into final executable programs. The most frequently used and free available compiler is the GNU C/C++ compiler, otherwise you can have compilers either from HP or Solaris if you have the respective operating systems. The following section explains how to install GNU C/C++ compiler on various OS. m We keep mentioning C/C++ together because GNU gcc compiler works for both C and C++ programming languages.

Quick Start with C

programming language is perhaps the most popular programming language. C was created in 1972 by

Dennis Ritchie at the Bell Labs in USA as a part of UNIX operating system. C was also used to

develop some parts of this operating system. From that time C programming language has been the

de facto programming language when fast programs are needed or the software needs to interact

with the hardware in some way. Most of the operating systems like Linux, Windows™, and Mac™ are either

developed in C language or use this language for most parts of the operating system and the tools coming

with it.

This course is a quick course on C Programming language. In our first lesson we will first write our first

C program. We will then learn about printing to screen, variables and functions. We assume that you are

familiar with at least one of the popular operating system

About C programs :

C programs with output illustrate various programming concepts - operators, loops, functions, single and double dimensional arrays, performing operations on strings, files, pointers, etc. Download executable files and execute them without compiling the source file. Code::Blocks IDE is used to write programs, most of these will work with GCC and Dev C++ compilers. The first program prints "Hello World" on output device.
