These are programs I wrote using Borland's Turbo C++ IDE on Intel Pentium machines over DOS / Windows Command Prompt. Note that Linux users may see an odd little character at the end of every file for some files written under DOS environment - remove it and you're good to go. Note that Windows users may see some files in one straight line for some files written under Linux environment - just re-format as you want and you're good to go. 1999 - 2005, Shekhar Sherikar Web: http://www.sherikar.com/shekhar Email: shekhar@sherikar.com
