Multiple Choice

Suppose you would like your code to perform several tasks: Use a For…Next loop with an InputBox to prompt the user four times for the price of four different T-shirts, then display each shirt price with a 25% discount in the ListBox lstResult. Which of the following code segments correctly performs these tasks?

• A) Dim intIndex As Integer
• Dim sngPrice, sngDiscountPrice As Single
• For intIndex = 1 To 4
• SngPrice = CSng(InputBox("Enter price of shirt " & intIndex.ToString))
• SngDiscountPrice = sngPrice * 0.75
• LstResult.Items.Add(sngDiscountPrice)
• Next
• B) Dim intIndex As Integer
• Dim sngPrice, sngDiscountPrice As Single
• For intIndex = 0 To 4
• SngPrice = CSng(InputBox("Enter price of shirt " & intIndex.ToString))
• SngDiscountPrice = sngPrice - (.75 * sngPrice)
• Next
• LstResult.Items.Add(sngDiscountPrice)
• C) Dim intIndex As Integer
• Dim sngPrice, sngDiscountPrice As Single
• For intIndex = 1 To 4
• SngPrice = CSng(InputBox("Enter price of shirt " & intIndex.ToString))
• SngDiscountPrice = sngPrice * (.25 - sngPrice)
• LstResult.Items.Add(sngDiscountPrice)
• Next
• D) Dim intIndex As Integer
• Dim sngPrice, sngDiscountPrice As Single
• For intIndex = 0 To 4
• SngPrice = CSng(InputBox("Enter price of shirt " & intIndex.ToString))
• SngDiscountPrice = sngPrice * 0.25
• LstResult.Items.Add(intIndex & " " & sngDiscountPrice)
• Next
