Question

Your software company was invited to provide a proposal for a company in Australia. You currently have the cost in US dollars and need to convert the prices to the Australian dollar. Write a 2-part program using Ruby, Java®, or Python. Part 1: Write a function to gather the following costs from the user: Travel Cost: $9,800 Hotel Cost: $3,500 Rental Car Cost: $1,600 Labor Cost: $15,500 Part 2: Write a function to convert the costs from United States dollar (USD) to Australian dollar (AUD). Note: Look up the current USD to AUD exchange rate to use in your function. Test the program 3 times by providing different costs in USD. Provide the code and take a screenshot of the output, then paste the screenshot(s) into a Microsoft® Word document. Write a half-page response in the same Microsoft® Word document to address the following: Provide a manual for the user explaining how to use the program. Explain what type of user input validations you should have. What happens if the user enters a negative number? What happens if the user puts a $ in the input?

Answer 1

Python Program:

def getInput(st):
   """ Function that reads the input from user """
   try:
       # Reading costs from user
       cost = float(input("Enter " + st + " : "))
          
       # Checking for negative amount
       if cost < 0:
           print("\n Please enter positive amount.. ")
           getInput(st)
          
       # Returning cost  
       return cost
      
   except:
       # Printing error message
       print("\nError: Please input positive amount with out $ symbol")
       getInput(st)

      
def convert_USD_AUD(USD):
   """ Conversion from USD to AUD """
   # Conversion Factor
   # 1 USD = 1.47923 AUD
   return (USD * 1.47923)
  
  
def main():
   """ Python program that converts USD to AUD """
   # Reading costs from user
   travelCost = getInput("Travel Cost")
   hotelCost = getInput("Hotel Cost")
   rentalCarCost = getInput("Rental Car Cost")
   laborCost = getInput("Labor cost")
  
   # Converting Cost from USD to AUD
   a_travelCost = convert_USD_AUD(travelCost)
   a_hotelCost = convert_USD_AUD(hotelCost)
   a_rentalCarCost = convert_USD_AUD(rentalCarCost)
   a_laborCost = convert_USD_AUD(laborCost)
  
   # Printing costs in AUD
   print("\n\n Costs in AUD: \n")
   print("\n Travel Cost: %.2f"%(a_travelCost))
   print("\n Hotel Cost: %.2f"%(a_hotelCost))
   print("\n Rental Car Cost: %.2f"%(a_rentalCarCost))
   print("\n Labor Cost: %.2f \n\n"%( a_laborCost))
  

# Calling main function
main()

If a negative number is entered, user will be prompted again...

If an amount is entered with dollar symbol, user will be prompted again...
