uh?

what is your question?

and what is:

mid (S,n1,n2)

?

pls share the whole context

[graceful egret]

And could you share what you've written? At first glance you want a substring and are passing in a start and end index?

Mid(S, 3, 2) S=Thomas
the answer is "om"

[graceful egret]

So it creates a substring of Thomas, starting at the third character (o), and of length 2.

[neat hare]

but the explain is "returns a set of n2 characters starting at n1 in the string S"

i don't what is the meaning

[graceful egret]

that's what I said

n2 = 2
n1 = 3
Thomas
1234567
--**----

[neat hare]

if mid(S, 3, 5) with S = "Thomas" and mid(S, 2, 3) with S = "Thomas"

[graceful egret]

I'd expect the first one to give an indexoutofboundsexception
