Exam coming up, I have questions I need help answering.
I have an upcoming exam and I don't have access to my professor and I have questions that the book is not clarifying for me. The book that the class is using is Murach's Visual Basic 2008.
iI will list the questions will by numbers. I understand that there are alot of questions here but I really need a good grade on this exam and these are the areas that I am still unsure of. Some of the questions, I have tried to answer and I posted a comment in (), it my guess is correct could you annotate so. If not could you help me get on base.
I am taking the exam tomorrow at 11. I have been buried in this book for a couple of days now and I need help. I am using this site as a last resort. I figured individuals on here are much more proficient than myself so I mine as well ask the experts.
I want to thank anyone in advance that is willing to answer any of these questions for me. God Bless and Happy Veterans Day. I myself am an "Iraq Veteran" in 2003.
1. Here is the code, I understand what it does but I don't know how to apply it. (example inputing in numbers). I realize that default is 0. But on the questions the professor will have this code and say input a number what would the answer be? I don't know how to do that.
Input 3 as an example:
Dim sum As Integer
Dim i As Integer
For i = 0 to 4
sum += i
Next
Answer?:
Same problem but different format.
Dim sum As Integer
Dim i As Integer = 2 to 12 Step 2
sum += i
Next
Answer?:
Same problem but different format.
Dim sum As Integer
Dim i As Integer = 25 to -15 Step -10
iSquared = i ^ 2
sum += iSquared
Next
Answer?:
For loop that calculates a future value
D
im monthlyInvestemnt As Decimal = 100
Dim monthlyInterestRate As Decimal = .01D
Dim months As Integer = 120
Dim futureValue As Decimal
For i As Integer = 1 To months
futureValue = (futureValue + montlyInvestemnt) _
* (1 + monthlyInterestRate)
Next i

Answer?:
For i As Integer = 2 To 12 Step 2

Next
sum = 42 (2+4+6+8+10+12)

Next
sum = 42 (2+4+6+8+10+12)
Dim sum As Integer
Dim iSquared As Integer
For i As Integer = 25 To -15 Step -10
iSquared = i ^ 2
sum += iSquared
Next
Answer: sum = 1125 (625 + 225 + 25 + 25 + 225) ((25 * 25) + (15*15) + (5*5) + (-5*-5) + (-15*-15))
Dim iSquared As Integer
For i As Integer = 25 To -15 Step -10
iSquared = i ^ 2
sum += iSquared
Next
Answer: sum = 1125 (625 + 225 + 25 + 25 + 225) ((25 * 25) + (15*15) + (5*5) + (-5*-5) + (-15*-15))

FutureValue = 23233.90763519401698355733

Dim months As Integer = 120
Dim futureValue As Decimal
For i As Integer = 1 To months

Thank you very much for the information, it is much easier than I though, I was looking at it the wrong way. The last post though.
I am confused how you got this answer, I am a business major, I understand the future value of money very well. I understand what I am looking at for info. But where did you come up with the amount? The amount that I come up with on my financial calculator is this.
PPY:12
N:120
I: 10%
PMT: 100
FV: 20484.49
Regardless to the answer, am reading this right though?

I get it now, thank you. I was missing something.
Dim i As Integer
For i = 0 to 4
sum += i
Next
--> answer: sum = 10 (0+1+2+3+4 )
