You have already been told that your expectations are wrong here.

Let me just add this note: strrev() is a non-Standard function, so I don't
know how it's specified in Borland C++. But if it's close to
http://makeashorterlink.com/?Y16221AF6 (aka http://developer.novell.com/ndk/doc/libc/index.html?page=/ndk/doc/libc/libc_enu/data/sdk1615.html
, which might wrap), then the above call has undefined behavior.

sttrev() as specified by Novell modifies the character array its argument
refers to. OTOH, modifying a string literal such as " [12345] " has undefined
behavior.
