 A join  A join has a single exit point, that is traversed when all the input activities have occurred.  A merge  A merge (same symbol than the decision point) has a single exit and is traversed when any one of the input activities occurs.  A fork  A fork has one entry point and multiple exits to activities that can be done in parallel

Ask for the interest rate (e.g., “5” means five percent). Allow for fractions, as in Ask for the principal in $ Ask for the number of years (1-30) Ask the user whether he/she wants to see (a) the interest, (b) the sum of principal + interest, or (c) both a and b (default). More than $0 Less or equal 0 or more than 10 Less than 1 or more than 30 Ask for more? (y=yes) Print Output abanything else y For this assignment assume a “competent” user

Interest = Principal * [(1+ Interest Rate) t – 1] "Principal" is the same as "capital" pay attention to the unit of measure!

are named places in memory where you store information. To create a variable, you declare it (Dim) and you tell the computer what type of info you want to store in it (e.g., an integer, a double, a string, a range). Dim myInterest as double = 0 Dim userInput as string = “Stefano”  To change its content, you use the assignment operator “=” myInterest = 0.05  To use its value, you just write its name Dim newVariable as double = 0 newVariable = myInterest * 2

 Are objects with properties and behaviors.  No need to pre-specify what kind of info you want to store in them.  Examples: Range("A1").Value = “My Excellent Calculator” Range("A1").Font.Bold = True Range("A1").ColumnWidth = 30 Range("A3").Value = "Interest is" Range("B3").Columns.NumberFormat = "$#,##0.00_);[Red]($#,##0.00)" Range("B3").Value = interest

Recognize the patterns & follow the examples

... creditRate > 50% Dim creditRate as Double ‘ More instructions… If creditRate > 0.5 Then Range("A10").Value = "Approved!" Else Range("A10").Value = "Rejected" End If Print “Approved” Print “Rejected”...

cr. rate > 50% If creditRate > 0.5 Then Range("A10").Value = "Approved!" End If Print “Approved”...

AND : if (creditRate > 0.5 ) And (age > 21) OR : if (creditRate 21) NOT : if Not (age = 21) alternatively you can use If age <> 21

Dim inputFromUser As String Do inputFromUser = InputBox(“Amount of principal?") principal = Double.Parse(inputFromUser) Loop While principal <= 0 Ask the user the amount of principal in $ Principal <= $0

Ask the user the amount of principal in $ Less than / equal to $0 Do ‘ Task A Do inputFromUser = InputBox(“Principal?") principal=double.Parse(inputFromUser) Loop While (inputFromUser <= 0) ‘ Task B inputFromUser = InputBox(“Want to quit?") Loop While (inputFromUser <> “y”) Task B want to quit (n=no)? n Task A y

interest = Principal * [(1+ Interest Rate) t – 1] 1. interest = principal * ((1 + interestRate) ^ t) - 1) 2. interest = principal * (Application.WorksheetFunction.Power((1 + interestRate), t)-1)

Select Case textFromUser Case “a” Range(“B5").Value = “This is case a" ’ More instructions… Case “b” Range(“B5").Value = “This is case b" ‘ More instructions… Case Else Range(“B5").Value = “this is the Default“ ‘ More instructions… End Select Ask the user Print Output a b default

Dim number As Integer ‘other code in here... Select Case number Case 1 To 5 Range("A1").Value("Between 1 and 5, inclusive") Case 6, 7, 8 Range("A1").Value("Between 6 and 8, inclusive") Case 9 To 10 Range("A1").Value("Equal to 9 or 10") Case Else Range("A1").Value("Not between 1 and 10, inclusive") End Select Source: MSDN
