help with simple OpenGL

Hi iam new to openGL an i want to know how to print vertex using openGL in a 2d plane.
suppose i want to print p(2,5),q(3,2) etc on the 2d plane.
all in know that there is a function for printing points but i dont know how to use/write the code please help.
I have basic knowledge of C though…

I suggest you google for OpenGL tutorials. There is a nice one on modern OpenGL at http://www.arcsynthesis.org/gltut/ or the more traditional ones at http://nehe.gamedev.net/.
