Multiple Choice

Which of the following code fragments calculates the average of 5 numbers input with an input box, and displays the result in lblResult?

• A) intCount = 5
• intSum = 0
• Do While intCount = 5
• IntSum = CInt(InputBox("enter a number"))
• SngAvg = intSum / intCount
• LblResult.Text = sngAvg.ToString()
• Loop
• B) intCount = 0
• intSum = 0
• Do While intCount < =5
• IntValue = CInt(InputBox("enter a number"))
• IntSum = intSum + intValue
• Loop
• SngAvg = intSum / intCount
• LblResult.Text = sngAvg.ToString()
• C) intCount = 0
• intSum = 0
• Do While intCount < = 5
• IntValue = CInt(InputBox("enter a number"))
• IntSum = intSum + intValue
• IntCount += 1
• Loop
• SngAvg = intSum / intCount
• LblResult.Text = sngAvg.ToString()
• D) intCount = 0
• intSum = 0
• Do While intCount < 5
• IntValue = CInt(InputBox("enter a number"))
• IntSum = += intValue
• IntCount += 1
• Loop
• SngAvg = intSum / intCount
• LblResult.Text = sngAvg.ToString()
