I need help creating flowchart

1. A business (the user) allows a client to order Four different products a) Widgets @ $10.50 each b) Gadgets a $12.75 each c) Gidgets @ $7.50 each d) Thingees S5.50 each 2. The user must manually input the quantity ordered a) Customer ID number b) The user may order 1 or more of the four different products (e.g. 4 Widgets, 5 Gadgets, 1 Thingee OR only 3 Gidgets). We will need four quantities representing the four products c) The only valid values are whole, positive numbers including zero (they may not want one ornmore product types e.g. 0 Gadgets). You cannot order a fractional item such as "1.4 7 dgets" d) Yovhave to add logic for error checking (e.g. for negative quantities, zero is a val. 3. Subtotal each product ordered (e.g. 5 Widgets @ $10.50 $52.50 or 1 Gidget a S7.50- 4. 5. 6, 7. S7.50) Compute the Order Total of all four possible subtotals Compute the Shipping and Handling charge of 10% (e.g. 0.1) based on the Order Total Compute a Sales tax of 8.75% based on the Order Total Display the following a) The subtotal for each positive value quantity ordered (e.g. if you ordered 0 Widgets that should not appear on the display) b) Display the Order Total c) Display the Shipping and Handling Charge d) Display the Sale Tax e) Display the Grand Total (what intermediate calculations compose this?) 8. Ask the user if they wish to input another order a) Yes - calculate another customer order b) No - end program
