TASK 2 - Programming Basics: LOOPS

Task 2.1

FOR Count 1 TO 100OUTPUT Count

ENDFOR

A Post-Condition loop (POST-TEST):Declare Count: IntegerCount 1REPEAT

PRINT CountCount Count + 1

UNTIL Count > 100

A Pre-Condition loop (PRE-TEST):Declare Count: IntegerCount 1WHILE Count <= 100

Print CountCount Count + 1

ENDWHILE

Task 2.2 Modify the solutions from Task 2.1 to:

1 Prompt for the input of the Start and End value.2 Output all the numbers between the Start and End values that are exactly divisible by 3.

For the Built-in functions list, refer to the Appendix on page 7.

1 A Post-Condition loop (POST-TEST):

Declare Count, StartValue, EndValue: IntegerInput StartValueInput EndValueCount StartValueREPEAT

IF MOD(Count, 3) = 0 Then Print Count

ENDIFCount Count + 1

UNTIL Count > EndValue

2 A Pre-Condition loop (PRE-TEST):Declare Count, StartValue, EndValue: IntegerInput StartValueInput EndValueCount StartValueWHILE Count <= EndValue

IF MOD(Count, 3) = 0 Then Print Count

ENDIFCount Count + 1

ENDWHILE

TASK 3 – Program design and coding

A string exists in CamelCase format. For example: “ThisIsACamelCaseString”.

A procedure is required that will: Prompt for the original string Separate each word of the string Store each word in a separate array element Fill unused array elements with a rogue string such as “(Empty)”.

After processing the preceding example, the array contents will look like this.

ThisIsACamelCaseString(Empty)(Empty)(Empty)(Empty)

Task 3.1 Declare an arrayUse pseudocode to declare the array that can be used to store the separate words of the original string. You can assume that the original string will contain no more than 10 separate words.

Declare ArrayWords: Array[0:9] of String

Task 3.2 Expression of the requirements using structured English

Ask the user to enter the original string Use a regular expression to insert a space between each word in the original string Split the new string by space into the array Loop into the array and for each empty location found, add the word “Empty”

Task 3.3 Write the pseudocode for this design

Declare ArrayWords: Array[0:9] of StringDim OriginalString, NewText As StringInput OriginalStringNewText = InsertSpaceBetweenCamelCase(OriginalString)ArrayWords = NewText.Split(“ “)For Count = 0 to 9

IF ArrayWords(count) = ““ THENArrayWords(count) = “Empty”

End IFEndFor

Task 3.4 Write the program code for this design

Module Module1Sub Main()

Dim arrayWords() As StringDim OriginalString, NewText As StringOriginalString = Console.Readline()‘Use regular expression to have a space between the wordsNewText = Regex.Replace(OriginalString, “([a-z](?=[A-Z0-9])|[A-Z][a-z]))”, “S1 “)arrayWords = NewText.Split(“ “)‘Change the size of the array dynamically to 10 while retaining contentReDim Preserve arrayWords(9)For count = 0 to 9

If arrayWords(count) = “” ThenarrayWords(count) = “Empty”

End IfNext

End Sub

Task 3.5 Amend the program code in Task 3.4 to print out the content of the array

Module Module1Sub Main()

Dim arrayWords() As StringDim OriginalString, NewText As StringOriginalString = Console.Readline()‘Use regular expression to have a space between the wordsNewText = Regex.Replace(OriginalString, “([a-z](?=[A-Z0-9])|[A-Z][a-z]))”, “S1 “)arrayWords = NewText.Split(“ “)‘Change the size of the array dynamically to 10 while retaining contentReDim Preserve arrayWords(9)For count = 0 to 9

If arrayWords(count) = “” ThenarrayWords(count) = “Empty”

End IfConsole.WriteLine(arrayWords(count))

NextEnd Sub

Task 3.6 Test data to test the code thoroughly.

Type of test data Example Justification

Normal test data ThisIsACamelCaseString Valid data - accepted

Abnormal test data Abc #2ydfj Invalid data - rejected

Extreme test dataNot applicable for this sample, because there is no numeric data involved.

None
