What Does the code DO?
----------------------

Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.)

 Program flow Explained
 ----------------------
 * Open the File to be encrypted for Binary Access Read(Say Source File)
 * Open a temparory file where encrypted data is stored  for Binary Access Write(Say Destination     File)
 * Loop through the Source File Byte by Byte
 * For each byte read from the file, Complement the data. (Using Not operator (in C we have to       use "~" operator)
 * Write Complemented Data to Destination File
 * Delete the Source File
 * Rename Destination file as Source File(Now Encryption is over)
 
 How to Decrypt?
 ---------------
 Since we have complemeted and saved byte by byte, simply complement it again for reproducing he   original file.(ie : Same Code can be used for both encryption and Decryption.)

 Code is attached herewith.
