1. ONLINE COMPILER
2. Offers users to (a) Register (b) Log In (c) Directly test run their code. HOME PAGE
3. REGISTER NEW USER 1. Form validation is done at the Client side itself. 2. On clicking Create Account! register.php script is called. 3. User details are then added to the user’s database and new user is created. 4. User is then redirected to Log In page.

8. 1. User can tick input box to provide input to the executable of the coded program. 2. User can also pass command line arguments to the program under execution.
9. HOME PAGE – BEHAVIOR DESIGN Code Editor Area Input Area Choose language Run code User writes code here. User provide inputs here. Hit this button to execute code. Executes a PHP script Command line arguments User pass command line arguments here.
10. OTHER FEATURES ¢  Save —  Allows registered user to save his/her code in its dedicated directory. ¢  View —  Allows registered user to view any of his/her previous saved code files. ¢  Edit —  Allows guest user to edit current code file many number of times. —  Allows registered user to edit any previous code files any number of times. ¢  Manage work space —  It enables registered user to keep track of his/her work space (its directory). —  It can include - deleting previous files, making new sub directories etc.
11. ¢  Public —  Users can select this option to make their code visible to all the users of the application website. ¢  Sample codes —  Users will get code sample of all the supported languages to help them understand the How to use the Interface. —  After a language is selected, sample link will be visible to the user(Gen.) and on clicking sample a sample code will be placed into the code editor area. —  User can now execute that sample program to see the result.
