The program is an illustration of loops
<h3>What are loops?</h3>
Loops are program statements that are used to perform repeated operations
#This gets the product name
product = input("Product: ")
#This gets the quantity
quantity= float(input("Quantity: "))
#This initializes the total quantity to 0
total = 0
while(product.upper() != "XXX"):
#This calculates the total price
total+=price
#This gets the product name
product = input("Product: ")
#This gets the quantity
quantity= float(input("Quantity: "))
#This prints the total quantity
print(total)
