Description: This program basically comparies user input
lottery number to the computer generated lottery ticket
number after comparing each digit, it show out put of
number of digits same in computer generated lottery
number and user entered lottery number.
Then there are some pre-fiexed prizes in the program:
If
1. One digit     =  prize of Rs.100
2. Two digits    =  prize of Rs.200
3. Three digits  =  prize of Rs.300
4. Four digits   =  prize of Rs. 400
5. Five digits   =  prize of Rs. 500

and program will output one of these prizes accourding to
the number of digits matched.
