Algorithm: Retail Price Calculator
1. Create a class named RetailPriceCalculator.
2. Define a static method in the class:
- Method name: calculateRetail
- Input: wholesale_cost (float), markup_percentage (float)
- Output: retail_price (float)
3. Inside calculateRetail method:
a. Check if wholesale_cost is less than 0:
- Return 0.00
b. Check if markup_percentage is less than -100:
- Return 0.00
c. Calculate retail_price as wholesale_cost * (1 + markup_percentage / 100).
d. Return retail_price.
4. Define a main function:
a. Initialize a while loop:
- Prompt the user to enter the wholesale cost.
- If the user enters -1, exit the loop.
- Convert the input to a float.
- If wholesale_cost is less than 0, print an error message and continue the loop.
- Prompt the user to enter the markup percentage.
- If the user enters -1, exit the loop.
- Convert the input to a float.
- If markup_percentage is less than -100, print an error message and continue the loop.
- Call the calculateRetail method with wholesale_cost and markup_percentage as arguments.
- Print the retail price with two decimal places.
5. In the main block:
a. Call the main function if the script is executed directly.
6. End.
