Googling for solutions is ok, copying and pasting from a classmate is not.

3. Homework
H4 - Fin Cal Part II

4. It begins with figuring out what needs to be done
Hey, I really liked your financial calculator! Could you add to it a table that shows interest and principal from year 0 to the end?
User perspective
“Use cases”
Talk about it
Sketch it
Show it
Prototype with paper and pencil

5. Activity Diagram (part II) Simple Financial Calculator
User inputs principal, years, and interest rate
User presses “print table” button
Principal, Year, or Rate is missing
Alert the user
Print and format table header
i > number of years
Format data and autofit the columns
i <= number of years
Print the ith row of data

6. You Do The Talking Name Learning objectives

8. Variables 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 the variable stored value, you just write its name
Dim newVariable as double = 0
newVariable = myInterest * 2

9. Excel CELLS 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
Range("A2", "B10").Value = "Wow!"

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

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

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

15. Implementing a For…next loop
Print and format table header
i > number of years
Format data and autofit the columns
i <= number of years
Print the ith row of data
For i As Integer = 0 To years
Range("H4").Offset(i, 0).Value = i
interest = principal * ((1 + interestRate)^i -1)
Range("H4").Offset(i, 1).Value = interest
Next
