Sample Functional and Non Functional Requirements
There is nothing wrong with learning by example. These are sample functional requirements for 'HELLO' applications. Hopefully, you will be able to translate these into your own in a simple way. If I had to provide some tips they would be as follows.
TIPS!

Notes
As you can see as simple as these are they are very short and clear. A real application or programming effort will have many of these. If you find you are getting too many of these then you are probably working at a level too low for general requirements gathering and are encroaching on low level design or technical specifications.
