sry but nobody can just post simple code for that^^
When you want to display model on the screen you must go through some steps, which are not really hard, but some work.
First you need a model file which is in a specific format, you want to use a format which is widly used and supported so you can use common tools to create your models. Most you because of this the OBJ format at first, because it is really easy to parse yourself and is very basic and nearly every tool supports it.
After that you will have some model data in your memory which needs to be converted to some data which can be used with OpenGL.
When you ave this you finally have to choose how to render it, i.e. glBegin or Buffer Objects and how to you handle materials(textures, properties like shininess).
I started out myself parsing OBJ and now finished(btw
) a lib to read the OpenCTM
format, take a look how I did it DarwinsBox: geometrie/io
