Added initial version of Hello World example.

New page

The Hello Word example looks like this:

<code>[eiffel,N]
class
ROOT_CLASS

create
make

feature -- Initialization

make is
-- Creation procedure.
do
io.put_string ("Hello World!")
end

end
</code>

To compile this sample, we suggest that you use the '''Basic application''' wizard to create the project. And once the project is created to update the ROOT_CLASS with the above content. The required steps are:
# Start EiffelStudio
# Select the '''Basic application''' entry from the ''Create project'' section and click '''Create'''
# In the new dialog that appears, enter the location of the project and select "OK"
# Choose your target, that is to say whether you are compiling for C code ('''sample''') or for .NET ('''sample_dotnet''')
# Once the compilation is done, type ROOT_CLASS in the Class entry in the ''Address Bar'' toolbar. This will load the ROOT_CLASS in the editor.
# Enter the above text for ROOT_CLASS
# Click the '''Compile''' button in the ''Project Bar'' toolbar.
# Click the '''Start''' button in the ''Project Bar'' toolbar to start the execution and see the output of your program.
