why don't you use files so even if your program exits, Data will be available

plz tell me how can i add purchase in choice menu ...

Do you seriously not know how to add PURCHASE to the menu?

...and it gets added to the program ...

Follow the pattern set forth for the other items.

...and it works as a software ...

No idea what this means.

...and keep the record feeded in it.

Output the record to a file to be read next time the program starts.
