I need is the program will firstly allow the user to select a file to be encryted.
After this file is opened, the characters are read, converted as required, and placed into a 20 element array one
by one.Once the array is full, (ie 20 characters), they are written out to the new file in reverse.
This continues until all characters aer done, remebering that the last set of characters will probably be less than 20.
The user should be able to view the encrypted program on the screen, if they wish to.
This program written in pseudocode would be nice as well
