Thread: Is there a way that I can write on top of a line in C graphics.h or OpenGL library?

I have a question about graphics.h library of C. I am trying to visualize a suffix tree in C with using graphics.h library or OpenGL library it doesn't matter. How can I write the suffixes of the given word on top of the lines? I couldn't find a way to do it. For now I can print out the suffixes like this: If the given word is (xabxac$) it will print out

1. $[6]
2. a[-1]
3. bxac$[1]
4. c$[]
5. bxac$[2]
6. c$[5]
7. xa[-1]
8. c$[3]
9. bxac$[0]

So any help how can I visualize this like a tree in C?
