Structured English/Flowchart to Pseudocode

Example - Structured English

A customer is buying an item. If the customer has a discount code, they receive 10% off the price. Otherwise, they pay the full amount. The program should ask for the item price and whether they have a discount code, then calculate and display the final price.

Step 1 - Structured English

1. Ask the user to enter the price of the item

2. Ask the user if they have a discount code

3. If they do have a discount code
    → Calculate 10% off the price
    → Subtract the discount from the original price

4. Otherwise
    → The price stays the same

5. Output the final price

Step 2 – Identifier table

Step 3 – Pseudocode

// Ask for item price
INPUT ItemPrice

// Ask if user has a discount code
INPUT HasDiscount

IF HasDiscount = TRUE THEN
    DiscountAmount ← ItemPrice * 0.10
    FinalPrice ← ItemPrice - DiscountAmount
ELSE
    FinalPrice ← ItemPrice
ENDIF

// Output the final price
OUTPUT "The final price is ", FinalPrice

Structured English/Pseudocode to Flowchart

Example - Pseudocode

INPUT Number

IF Number MOD 2 = 0 THEN
    OUTPUT "Even"
ELSE
    OUTPUT "Odd"
ENDIF

Step 1 – Identifier table

Step 2 – Flowchart structure
