Short answers 1. It lets you use the code by calling that module instead of rewriting the code. 2. It has a header and a body. The header is the starting point of the module and then the body is where the code is written and the module ended. 3. The program will stop executing 4. A local variable is a variable that is declared indie of a module and can only accessed inside of its own module 5. A local variable’s scope usually begins at the variable’s declaration and ends at the end of the module in which the variable is declared. 6. Passing byval means that only a copy of the variable is passed. Passing byref means that the variable is passed and can be altered in that module. 7. Any statement in a program can change the value of a global variable.

Algorithm Workbench 1. Sub timesTen( byref argument as integer, byref product as integer)
Product = argument * 10 5. sub getNumber(byref number as integer) Console.wroteline(“enter your number”) Number = console.readline() 6. At the end it should display both x and y as a 0 7. at the end of this is should make the variables a set to 1 and b set you 3.4 and display 1 and 3.4

Module Module1

Sub Main() Dim kilo As Decimal = 0 Dim miles As Decimal = 0

Console.WriteLine("Please neter how many kilometers to have traveled.") kilo = Console.ReadLine()

mathStuff(kilo, miles) Console.WriteLine("You have traveled," & miles & " miles.") Console.ReadLine() End Sub

Sub mathStuff(ByVal kilo As Decimal, ByRef miles As Decimal)

miles = kilo * 0.6214

2. Module Module1

Sub Main()

Dim item As Decimal = 0 Dim stateTax As Decimal = 0.04 Dim countyTax As Decimal = 0.02 Dim stateTax1 As Decimal = stateTax * item Dim countyTax1 As Decimal = countyTax * item Dim totalTax As Decimal = stateTax1 + countyTax1 Dim totalItem As Decimal = totalTax + item 'calls askInfo(item) mathstuff(stateTax, countyTax, item, stateTax1, countyTax1, totalTax, totalItem) Console.WriteLine("The items cost is " & item & " , the state tax is currently 4% and the county tax is at 2%. The total amount of tax for this item is " & totalTax & " and the total of the item plus tax is " & totalItem & "") Console.ReadLine() End Sub

Sub askInfo(ByRef item As Decimal) Console.WriteLine("Please enter the amount of the item.") item = Console.ReadLine() End Sub Sub mathstuff(ByVal stateTax As Decimal, ByVal countyTax As Decimal, ByVal item As Decimal, ByRef stateTax1 As Decimal, ByRef countyTax1 As Decimal, ByRef totalTax As Decimal, ByRef totalItem As Decimal) stateTax1 = stateTax * item countyTax1 = countyTax * item totalTax = stateTax1 + countyTax1 totalItem = totalTax + item End Sub
