My student programmed a pretty cool code (which I have no idea what it does) but we keep getting an error message
How do you know that it is cool if
(a) you don't know what it does
(b) it does not compile, upload and run
As the error is
MSpanList_Insertthen a wild guess would be that an insert of data into an array has strayed outside the bounds of the array but until we see the actual code (in code tags please) then we are working in the dark.
