Hello Suman,
1. Anything below Borland C / C++ version 3.1 compiler for DOS is
inherently unreliable. Upgrade to 3.1 if you are working in DOS.I had a
similar problem with BC version 1.0. Are you using TC ? They suck :(
2. There is a typo, I guess. No mention of variable prev in the
declarations. This is _not_ causing your problem.
3. I do not have access to BC right away but reading the header
file dos.h would be of help. Tip : Do not trust the documentation/help
pages ;)
Regards
Shourya
