Answer / tushar srivastava

Hello Friends,
I am having a question here....
If you can save a binary number in at maximum four bytes,
then why are you wasting 16 bytes for the same. This method
is not recommended by me lest you need to send data to some
output port. And even the previous method ie my method can
directly be used to transfer data though serial or parallel
port if needed. Ponder over it......
