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/.
