I need feed back on how to correct my pseudo code....Can someone help me please?

Question

I was given feed back from my instructor and I am not sure how to empliment these changes. Here is the feedback:

In your MAIN module you call a WELCOME MESSAGE module but you don't have one defined in the code.

Why do you have a variable named ItemName? Variable names should be descriptive
of what the are being used for.

In your INPUT module you first ask for the items name but not for the name of
the currency you want to convert. You then ask for the currency type but input the currency amount.

Your PERFORM CALCULATIONS module does not perform any calculations. You do set the sourcerate variable to different rates (but only for 4 of the specified currencies) You never perform the currency conversion.

Currency conversion

Canadian dollars rate: 1 U.S. dollar = 1.4680 dollars)
Mexican pesos 	(rate: 1 U.S. dollar = 9.5085 pesos)
English pounds 	(rate: 1.6433 U.S. dollars = 1 pound)
Japanese yen 	(rate: 1 U.S. dollar = 104.9200 yen)
French francs 	(rate: 1 U.S. dollar =  6.2561 francs)

Currency Conversion Design


Main module

Declare ItemName As String
Declare Currency type  As Real

Call Welcome message module
Call Input Data module
Call Perform Calculations module
Call Output Results module

Write “Welcome to the currency convertor database,”

End Program

Input Data module

Write “Enter the item’s name?”
    
      Input ItemName

Write “What is the currency type?”

      Input currency dollar amount

End Input Data module

Perform Calculations module

 If sourceCurrency is Dollar Then
    Assign sourceRate to 1.4680 dollars

ElseIf sourceCurrency is Pound Then
    Assign sourceRate to 1.6433 Pounds

ElseIf sourceCurrency is Yen Then
    Assign sourceRate to 104.9200 yen

ElseIf sourceCurrency is Francs Then
    Assign sourceRate to 6.2561 francs

End If

Output Results module
Write “The currency is”: ItemName

In your MAIN module you call a WELCOME MESSAGE module but you don't have one defined in the code. As the instructor said you call the welcome message module but there isn't one. You need to define a module named WelcomeMessage and have it perform the action of writing out the welcome message. Why do you have a variable named ItemName? Variable names should be descriptive of what the are being used for. Here you need two variables the amount of US currency that you need to convert to foreign currency and the name of the type of currency you wish to convert it into. At that he is saying that you need to name your variables something that will make sense to someone else that might come along later and maintain your code. I suppose that using something like DollarsToConvert as decimal and ConversionCurrency as string would work. In your INPUT module you first ask for the items name but not for the name of the currency you want to convert. You then ask for the currency type but input the currency amount. After renaming your variables this ought to make more sense. If you ask for the amount of US currency to convert and assign the value to the DollarsToConvert variable and then ask for the conversion currency and assign it to the ConversionCurrency variable you will have accomplished that. Your PERFORM CALCULATIONS module does not perform any calculations. You do set the sourcerate variable to different rates (but only for 4 of the specified currencies ) You never perform the currency conversion. The perform calculations module does not calculate the value of the foreign currency. If you switch on the currency type and then convert the currency by multiplying the DollarsToConvert by the conversion factor you will have calculated the value of the foreign currency after converting US dollars to yen or pesos or whatever.
