A large number of C-programs implementing different algorithms are given in the Blog. Most of the programs are provided in both text mode as well as in graphics mode. While text mode programs can be executed on any platform having a C-compiler, the graphics mode programs require an IBM PC (or equivalent) with WINDOWS operating system and Turbo C or Borland C compiler. So enjoy it... - Amit Upadhyay (amitwebhero@gmail.com)
