Do you mean writing text with OpenGL? OpenGL can’t do text editting you have to do that in your own code.

yes writing text with openGL.

i want to write 100 how can i write it with OpenGL??? tells me the code.

OpenGL does not have any direct support to writing text. You have to create some sort of bitmap of the text and render it as a texture on a quad. Google “drawing text in OpenGL” there are a lot of articles describing
different ways of doing this. Personnally I use a variation based on http://www.angelcode.com/products/bmfont/
