Question Formatting a string in do_score

I'd imagine I may be overcomplicating this, but if you wanted to do an ascii border around your score sheet similar to this

|

---

|
|Score information for %s               |      <----Fixed border
|

---

|

What is the best way to format the string to allow for a max character length that would keep the "border" the same, regardless of the length of the string 
(within limits of course)

Thanks
 

I'm trying to play with it and use justify to position, Was wondering more than anything if there is a cleaner way to design a border and keep it the same.

I think I've got it sorted through left/right justification. There is probably a more efficient way but for now this will work

No, left-right justification (%-30s, %30s) is the way to go for this in C; you'll probably not find a better way.

I use the exact same method Thomas uses. if you do a custom score sheet and want exact place holders you will use this a lot. Nothing better than seeing a custom score sheet with everything lining up correctly
