#Write a function, perishable, that has one parameter - number of items in the store. 
#The function reads the barcode (integer number) for each item and its price (floating 
#number). All perishable items in the store have EVEN barcodes. The function finds and 
#returns the number of PERISHABLE items that cost under 2 dollars. 
#Write main that reads the number of items in the store, calls function perishable to 
#find the number of PERISHABLE items that cost under 2 dollars. If there are NO such 
#items, the program prints appropriate message.
