Using Parallel One-dimensional Arrays To Calculate A Letter Grade?
Jul 27, 2011
The exercise prior to this one had us use two parallel arrays that store a letter grade (A, B, C, D, F) and the minimum points needed for each grade. The user input the points earned by the student and the program shows their letter grade. It took a minute, but I got that one done, and it does what it's supposed to do.This exercise has us modify that exercise to ask for the (via InputBox in MainForm Load event) total points possible. The grade is then determined by percentage of the total points possible. For instance, if x is the user input, an "A" would be 90% of x.

I have coded this not sure how to get it to display correctly to the lblGrade box. I have set it up for. Supposed to take the average of three grades and display the letter grade for the average of the three grades.
Here is the code
Public Class frmMain
Private Function CalculateGrade _
(ByVal txtTest1 As Decimal, ByVal txtTest2 As Decimal, _
ByVal txtTest3 As Decimal) As String
Dim AverageScore As Double

I have to write a program using 2 parallel arrays representing grade point and grades. The grade points range from 0 to 500, however, we are only to use the minimum points per each letter grade in " points " array. This is shown in the code below. You then enter a number from 1 to 500, representing the grade points, and in turn it spits out your letter grade.My problem is this. When I enter a number, say 200, I get a letter " D " grade instead of an " F " grade. It appears that every number range I enter gives me one letter grade less than what it is supposed to be. Also, any number 450 to 500, representing an " A " grade does not even register in my Grades Label.

ok so im having issues with this
Select Case a(b, 3)
Case "d"
c = 0
[Code]....
OK so a(b, 3) has either the letter d,e or f in it but when I try and read the multi dimensional array I don't think it picks anything up

I made an application that calculates course grades. The program runs perfectly except for the last part
The the final grade number comes from the label "lblCoursePts" and i want to put the letter grade in the label "lblFInalGrade" Here is what i have.
'Determine the final letter grade
Select Case lblCoursePts.Text
Case 90 To 100 : lblFinalGrade.Text = "A"

My assignment is to have a user enter in big integers using what i think is two parallel arrays. I got this far but now im stuck. I think i need to actually convert the text box input into an array but i do not know how to do that. I am all over the place in this project.

How do you enter in a code for an overall letter grade from a percentage given? I have a seperate box for the letter grade and a seperate one for a the percentage grade . I have it setup when an overall grade and possible grade is entered into boxes it will give me a grade percent but not a letter grade. How is that added? I am doing this for my course project but dont undersatnd the coding very well. I am just trying to pass the class.

I need someone with patience and can go through a solution with me from the Clearly Visual Basic book. I'm good with computers and can usually learn things relatively fast on my own time and in my own way, but I'm going to school for computer programming and, with certain things, I learn better with things explained to me rather than reading from a book. If someone has the time to go over this solution I'm doing and explain it to me in a way I'd have a better chance of understanding, I'd be truly grateful. I need a tutor, for lack of a better word. The lab I'm doing is from the Clearly Visual Basic book and the instructions are:
Code an application that displays a letter grade based on the averages of three test scores. Code the application using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B. If the average is at least 70 but less than 80 the grade is C. If the average is at least 60 but less than 70, the grade is D. If the average is below 60, the grade is F.

I have been struggling with my programming class from day one. I still can't seem to grasp the complete logic on how to write code. Anyhow, I have an assignment due that I am stuck on. Here is the assignment:
In this exercise, you code an application that displays a letter grade based on the average of three test scores. Open the Grade Solution (Grade Solution.sln) file, which is contained in the ClearlyVB Chapl8Grade Solution folder. Code the application,using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B.If the average is at least 70 but less than 80, the grade is C. Tf the average is at least
60 but less than 70, the grade is D. If the average is below 60, the grade is F.
You will be developing the code for the function on your own. Below the Public Class frmMain line, insert this function header:Private Function CalculateGrade(ByVal testScore1 As Decimal, ByVal testScore2 As Decimal, ByVal testscore3 As Decimal) As String
In the function, declare variables for the average score and the letter grade. Calculate the average, use IF/Elself statements to determine the letter grade, and return the letter grade. Create a subprocedure for the Click event for the btnDisplay button. It should call the CalculateGrade function with three arguments ( the three test scores from the text boxes), and display the returned value in the lblGrade box.

It is meant to average 15 user-input grades and then from there I have to provide the letter grade that corresponds with the average percent. I understand how to provide the corresponding letter grade, but I don't understand how to get the average. I've tried putting it into arraylist format

"I need to create a program that will allow the user to enter in 10 test grades from a class. I need to store these grades into an array, and use a loop to add up the total. Then I'll need to output the average, and the letter grade for the average using:
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D

That's all it needs to do. Here is some code that shows you that the only thing I know how to do is (allow the user to enter in 10 test grades from a class.) The rest I'm so lost on and have a crappy instructor. This assignment is due tomorrow, but the instructor is not available over the weekend.

I ma trying to create a program to calculate my math grade. The way my math teacher explained the grading scale was each test is worth 1 point and each quiz is worth .2 points.
So as an example (add both sides up then divide by both sides)
100 =1
80 = 1
15 = .2
18 = .2
213 divide by 2.4 which equals your grade of 88.75
There are more quizs and tests in the semester and I want the numbers to change with the number of quizs and tests entered. The only problem is I am not sure how to code it. I though I would use IF AND statements but I am not sure where to start.

Write a program that reads in a set of grades for a class.The program takes in the number of students in the class from the user. When the Get Grades button is clicked the program then reads in a grade (0-100) for each student using an inputbox. The program should then display the percentage of students who pass and the percentage of students who fail.The program should call a function to calculate the average grade for the class. Then finally the result is then displayed.

how can i sort too parallel arrays?
[Code]....
Those are the two arrays now when i try array.sort(strflavor,decamountsold) or array.sort(decamountsold,strflavor) they are not arraigned properly. I am trying to get them to sort by which flavor sold the least and which flavor sold the most. However when i sort them, the flavors are not matching up with the decimal values.

I just learned basic arrays, I'm writing a program the allows Professor Carver to display a grade based on the number of possible points he enters in the inputbox (strMax). Then the user enters the points he earned in the textbox (dblPoints)
Then I solve the percentage. dblResults = dblPoints/CDbl(strMax) The first step is to store the minimum percentage points in one dimensional array. I did that. The second step is to store the grades in one dimensional array. I did that. The arrays should be parallel arrays. Having trouble with it It then should display the corresponding grade from the strGrades array Not done. I'm having trouble to display arrays in that are parallel.

getting started with creating an index search for parallel arrays. When the user enters the specific "code", and presses enter, the information in the other arrays should be displayed based on its matching index. I'm pretty sure I use "For i = " but I'm lost. I have my arrays set up like this:

code(0) = "A"
code(1) = "H"

In Visual Basic 2005 is it possible to parallel sort three or maybe four arrays? I have a function that is trying to accomplish this but it only parallel sorts the second array with the Array that it is being sorted with. Here is the code
Sub ParallelListBoxSort(ByVal byList As ListBox, ByVal otherLists() As ListBox)
Dim ii As Integer = 0
Dim a As Integer = otherLists.Length
[Code]....
'listToArray' is just a function that converts a list to an 1-Dimensional array and 'setArrayToListCollection' just puts the array back into the appropriated list.

I am trying to use parallel.for in order to calculate the summation of all the values in an multidimensional array. I googled and found Click Here. However, this is just for one dimensional arrays. The LINQ does not work for multidimensional array. And when I use parallel.for it gives me different answer than the sequential approach.

Ive been working on a checkbook application for my visual basic class and I'm a little stumped..
To preface, the values I need to mess with include:
transaction type (checking or deposit)
DTP
check number ("dep" if deposit)
[Code].....
Below is the Change I need to make to my program...
"You will create a set of either collections or arrays (your choice but use just one or the other--don't mix them) scoped at the form/module level. These structures will store all of the input data needed for your checkbook transactions except for the running balance which will continue to be stored in a single module-scoped variable. That is, every input that users made in Assignment 3 will be stored in one of these arrays but you will not store any calculated values. You will not store the transaction type but will store "Dep" or a number in the check number array which will also indicate the transaction type. The Record button will add the current sale's data to these structures using either ReDim for the arrays or an appropriate technique for the collections. (You must ReDim your arrays so that the have just enough space for the data that is in them. Declaring the arrays with a large size with no facility to resize them is not allowed. Don't forget to use the ReDim Preserve syntax to retain the existing array contents when you resize them.)"
I don't know if I make a single array for all the values or if I create a separate one for each. If its a separate one for each I don't understand why an array is needed.

I need to know how to code a windows application program that will make it possible for customers to place orders online. Customers will have access to menu using a combobox,containing items available. The text file contains all menu items and the price of each item, as well as number of orders for each item. The file is created with a notepad containing 5 menu items.the first line contains the name of the item,second line contains the price and the third contains total number of orders which initially is 0. So far so good i know how to check if the file exists or not,and populating the the combobox, but ther's an instruction where i have ensure that the number of menu items does not exceed 100, and if so,should display an error message.and should validate to ensure that the total number of orders is>0,if not,re display the input box with a suitable message. Then on the save(menustrip),should write the whole textfile from arrays in memory,clear the combobox,display the message. Also has a process payment button where it should read through the arrays with a for next loop,then shouold write function called amount due,which recieves the total orders as a single data type,where the value for amount due is calculated as total orders*price.CAN SOMEONE PLEASE HELP ME OUT SINCE IM A BEGINNER IN VB2005.

I am trying to set up a number of two dimensional arrays that will be accessed from several forms in the project. I have set up a module to declare all public variables.When I declare the array (Using variables to determine the size of each dimension), when I go to run it, I get an out of index error.If I declare it them as public variables within the form, I don't get the error but then the input cannot be accessed from other forms.Am I completing incorrectly in the module or is there something else I ought to be doing.
The code within the form is
Dim Boardresult(NumBoards, Numteams) As Integer
Dim compass(NumBoards, Numteams) As Boolean
Where NumBoards and Numteams have been input and stored previously.
