Explanation / Answer

Please find the pseudocode/algorithm below.

1. Create a structure to represent Customer code. This structure will contain fields for storing customer order details, namely, Customer name, Ship code, order number, Item number, quantity, Extra price.

2. Now create another structure for storing shipping details. This structure will have fields for Shipping code, shipping type and the rate. Create an array of this structure and store all the shipping details into this array. These details are hardcoded instead of taking input from the user.

3. Now, get input the customer order details from the user and write the order details into file "customerOrder.dat". Keepon taking input from the user until he wishes to quit.

4. Now open the file "customerOrder.dat" in read mode.

5. Each of the lines in this file represents a Customer order. For each customer order, do the following:

a) Print the customer order details into the console.

b) Calculate the order total expense which can calculated as the sum of Order rate (ext_price) and

shipping cost. Then, display the shipping cost and total ordered expense.
