Pseudo Code for Generating a Quote

Overview

The following pseudo code outlines the logic and steps required to display a quote for selected products on behalf of a customer. It includes calculating the sub-total, VAT amount, and grand total.

Variables

• customer: Object representing the customer
• selectedProducts: List of products selected on behalf of the customer
• totalSubTotal: Float (initially set to 0)
• totalVAT: Float (initially set to 0)
• grandTotal: Float (initially set to 0)
• vatRate: Float (percentage representing VAT rate, e.g., 0.20 for 20%)

Main Steps

1. Get Customer Information

   • Prompt for customer ID or details
   • Retrieve customer information based on input
   • Validate customer exists

2. Get Selected Products

   • Retrieve a list of products selected for the customer
   • Validate selected products are available

3. Calculate Totals

   • For each product in selectedProducts:

     • Get productName

     • Get sellingPrice

     • Get quantity

     • Calculate subTotal for the product: subTotal = sellingPrice * quantity

     • Add subTotal to totalSubTotal

     • Calculate VAT: vatAmount = subTotal * vatRate

     • Add vatAmount to totalVAT

4. Calculate Grand Total

   • Calculate grandTotal: grandTotal = totalSubTotal + totalVAT

5. Display Quote

   • Print "Quote for: " + customer.name
   • For each product in selectedProducts:
     • Print "Product: " + productName
     • Print "Selling Price: $" + sellingPrice
     • Print "Quantity: " + quantity
     • Print "Sub-Total: $" + subTotal
   • Print "Total Sub-Total: $" + totalSubTotal
   • Print "Total VAT: $" + totalVAT
   • Print "Grand Total: $" + grandTotal

Pseudo Code

FUNCTION displayQuote(customerID)
    customer = getCustomerByID(customerID)
    IF customer is NULL THEN
        PRINT "Customer not found"
        RETURN

    selectedProducts = getSelectedProducts(customerID)
    IF selectedProducts is EMPTY THEN
        PRINT "No products selected for this customer"
        RETURN

    totalSubTotal = 0
    totalVAT = 0
    vatRate = 0.20  # Example VAT rate

    FOR each product IN selectedProducts DO
        productName = product.name
        sellingPrice = product.price
        quantity = product.quantity
        subTotal = sellingPrice * quantity

        totalSubTotal = totalSubTotal + subTotal
        
        vatAmount = subTotal * vatRate
        totalVAT = totalVAT + vatAmount
        
    grandTotal = totalSubTotal + totalVAT

    PRINT "Quote for: " + customer.name
    FOR each product IN selectedProducts DO
        PRINT "Product: " + product.name
        PRINT "Selling Price: $" + product.price
        PRINT "Quantity: " + product.quantity
        PRINT "Sub-Total: $" + (product.price * product.quantity)

    PRINT "Total Sub-Total: $" + totalSubTotal
    PRINT "Total VAT: $" + totalVAT
    PRINT "Grand Total: $" + grandTotal
END FUNCTION
