1. Consider the following function:

int func(int list[], int size)

{

int sum = 0;

for (int index = 0; index < size; index++)

sum = sum + list[index];

return sum;

}

1. Find the number of operations executed by the function func() if the value of size is 10.
2. Find the number of operations executed by the function func() if the value of size is n.
3. What is the order (Big-O notation) of the function func()?

2. Write a program for a clerk of Fresh Fruit Store so that the clerk will input the items that a customer buys and then print out the name, unit price, quantity, and cost of all item and the total cost as a receipt.

The program should do the following:

1. Define a new data type, fruit, as a C++ class. The class fruit should include:

• The name of the fruit in an item. Ex: Apple, Banana, ..
• The unit price of the fruit in the item. Ex: 0.99 ($/lb), 1.29 ($/lb), .
• The quantity of the fruit that the customer buys. Ex. 2 lbs, 3.5 lbs, ..
• Set the name, unit price, and quantity of the fruit in the item.
• Set the name of the fruit in the item only.
• Set the unit price of the fruit in the item only.
• Set the quantity of the fruit in the item only.
• Return the name of the fruit in the item.
• Return the unit price of the fruit in the item.
• Return the quantity of the fruit in the item.
• Return the cost of the item. (cost = unit price * quantity)
• Constructor with three default value

name = , unit price = 0.0, quantity = 0.0.

• Overloading the operator << to print the item in the following format:

Ex:

Apple $0.99/lb 3 lb $2.97

2. Write a function to show the name and unit price of each kind of fruit sold in the store.

3. Write a function to return the total cost in the shopping list.

4. Write a function to show all items in the shopping list, including the number, the name, the unit price, the quantity, and the cost of each item.

Ex:

Item Name Unit Price Quantity Cost

1 Apple $0.99/lb 3 lb $2.97

2 Grape $1.79/lb 2 lb $3.58

3 Banana $0.45/lb 2.2lb $0.99

:

5. Do the following operations in the main function:

• Create an array of type fruit as a shopping list. Suppose the max size of array is 100.
• Show the selection of the fruit in the storeAsk to select a kind of fruit and the quantity to buy, and store in an element of the array. Repeat the same operation until select 9 exit.
• Show all items in the shopping list, including the number, the name, the unit price, the quantity, and the cost of each item, and also show the total cost.

6. Show all items in the shopping list and ask whether to change the quantity. If yes, ask to select the number of the item needed to change. Write a function to change the quantity of the selected item by inputting the number of the item and the new quantity.
