Reference:

//product sales records including product code name information such as unit price amount 
//1) writing input function input 10 product sales record as above information 
//2) write the sum function calculation amount=number of unit price * 
//3) write sort function according to the amount of money from big to small order 

# include 
10//# define PRODUCTS according to the topic request 10 PRODUCTS
