Answer:
In DBMS, an index is a physical structure that stores the values for a specific column in a table. An index can be used to extract specific information from data and access records within a table more quickly without having to scan the whole table.
An Index can be made up of one or more columns of a table and each index maintains a list of values within that field that are sorted in ascending or descending order. Indexes cannot be seen by the users, but they are just used to speed up the queries and improve the performance of a database application
Answer:
total = 0
items = int(input("Enter the number of items ordered: "))
for i in range(items):
price = float(input("Enter the price of item " + str(i+1) + ": "))
total += price
if total < 200:
total += (items * 10)
print("Bill is $" + str(total))
Explanation:
*The code is in Python.
Ask the user to enter the number of items ordered
Create a for loop that iterates depending on the number of items ordered. Inside the loop, ask the price of each item and add it to the total
After the loop, check the total. If it is smaller than 200, add 10 for each item to the total
Print the total
