1. MainMenu form having :

a) button Open Answers File. When button is clicked; open Answer.txt, and read and

store the answers in an array of Strings. Close this file.

b) 2^nd  button Open Student Responses File. When button is clicked, do following: i. Open StudentResponses.txt file.

ii. Read number of students who sat the exam value and store it a variable.

iii. Then use loop to read student’s responses to questions. This loop runs up to number of students who sat the exam value read in i). For each line read, split record into an Exam Structure array that has an ID and responses field.

c) button titled Open Student Details File. When this button is clicked, do following:

a) Open and read StudentDetails.txt and store data into a StudentDetails structure array.

d) button titled Display Grades Results when clicked, should open up another form titled Grades Results Sheet on which in label should display grades results for class

This loop runs up to the number of students who sat the exam value read in i). For each line read, split the record into ID# and responses and store in ID and Responses array or into an Exam Structure array that has an ID and responses field. 

how to Create a MainMenu form. On this form implement the following functionality: a) Put a button titled Open Answers File. When this button is clicked; open Answer.txt, and readand store the answers in an array of Strings. Close this file. 

1. Rewrite the code below to read each line of a text file into an array named strFordModel.

DoWhile objReader.Peek = -1

strFordModel (intCount) = objReader.Readline( )

intCount + = 1

Loop

The first file contains the answers for the 20 questions and is called Answer.txt. The format of this file is TFTTTTTTFFTFTFTTTTFF.

Each character is a solution for the exam. The first character being the solution for question #1 and the last character the solution for question #20 respectively.

Dim j = 0

While j = 0

j = j - 1

Console.Write(“Hello”)

j = j + 1

End While

Question: If this code is executed, How many times will “Hello” be printed out?

Given three integers j, k and m

Build a function (in any development language) called SeqSummation, that calculates the sequence of summation as per:

j + (j + 1) + (j + 2) + (j + 3) + … + k + (k − 1) + (k − 2) + (k − 3) + … + m

Explanation: increment from j until it equals k, then decrement from k until it equals m.

Function Description

Create the function SeqSummation.

SeqSummation takes the following parameter(s):

• j integer

• k integer

• m integer

Program Output

• the value of the sequence sum

Example

• SeqSummation (5,9,6)

• i = 5, j = 9, k = 6

• Sum all the values from i to j and back to k: 5 + 6 + 7 + 8 + 9 + 8 + 7 + 6 = 56.

• Output: 56

Question

Description: Write a sorting function, that takes in an array of numbers (size n) and outputs the array of numbers as a list, in sorted sequence (highest value to lowest value)

Notes:

• Use any development language you wish

• Do not use any language’s in-built sorting function (example Javascript array.sort). We’re asking you to write the full sorting algorhythm yourself

Example

• simpleSort({1,2,3,4})

Output:

• 4,3,2,1

Question 8b. Bonus: Name the sorting algorhythm

For x = 0 To 100

For y = 5 To -10 step -1

If y = 0 Then

Exit For

End If

Console.Write("Hello")

Next

If x > 10 Then

Exit For

End If

Next

Question: If this code is executed, How many times will “Hello” be printed out?
