Comment by PrasannaKumar Muralidharan on "Why does this program not work as expected?"

Follow these steps:

Stop using Turbo C or Turbo C++ for god's sake
Start using library routines wherever possible. Use memset or implement your own memset. Do not use 2 loop for initializing array with 0
Modularize your code - split into functions
Print values at every step to see what goes on. Or better use a debugger and find out what's wrong in your logic.

Once you have done all this come back with your findings.
