  1. In any of the above four option(C, C++, Python, Scilab) we have following common components.

    • Text editor: is located on the left hand side. One can write source code in text editor. If you click on the text editor area, a virtual keyboard will appear and one can use it to write programs. Click back button (located at bottom left corner on Android status bar) to close the virtual keyboard.
