Code Writing *(simple logic)

‘declare variablesDim total as singleDim pepperoni as singleDim cheese as singleDim onion as singleEtc.

Private Sub chkPepperoni …If chkPepperoni.checked = true then

pepperoni = 2End if

Private Sub optLarge …If optLarge.checked = true then

large = 15.5End if

Private Sub cmdCalculateCost …total = pepperoni + large + small + cheese + onion + tomato + olive + baconlblOutputCost.text = “The cost of your pizza is $” & total

Code Writing **(better way)

‘declare variablesDim cost as single

Private Sub chkPepperoni …If chkPepperoni.Checked = True then

cost = cost + 2Else

cost = cost - 2End If

Private Sub optLarge …If optLarge.Checked = True then

cost = cost + 15.5Else

cost = cost - 2End If

Private Sub btnCalculateCostlblOutputCost.Text = “The cost of your pizza is $” & cost

**stuff in Pink was extra … level 3 without it – customers may change mind, and you uncheck .. the Pink code will then subtract the amount from the total

**also earned extra marks for only using one variable
