Hi

I have a string with 3 lines.

"ABC"
"ABC"
"ABC"

I want to remove second line.
I can remove all characters in the line but still the line there is.

"ABC"
""
"ABC"

I know in second line there is "\n"

I tried to use remove("\n") but It does not work.

So I need help with the problem.

Regards
Artur
