it is supposed to be a game
a cannon trying to shoot bunnies.
i've done the cannon,the environment and the cannon shots
and i've been given the ASCII code of the bunny,but i don't know how to load it in my program...

you need to parse the *.obj file and read out the vertices, normals, texture coordinates and so on. when you done reading them out you treat this data as you contruct your canon, f.e. upload to video memory or store them in a way appropriate for rendering.
the parsing isn't that difficult but that depends how familiar you are with the file format and how good your are at your programming language.
If you are using C++ you can take a look at this code: http://www.artifactgames.de/Code/Loader.zip
It will parse an OBJ and load the data into an internal struct. From there on you can easily integrate it into your own structures. Feel free to use / modify, as you wish.
