1. Create a Trip Calculator Windows application that can be used to determine miles per gallon for a given trip. Set the Form object properties of Name, ForeColor, BackColor, Text, and AcceptButton. The form should contain labels and textboxes to allow the user to input trip destination, miles traveled, and gallons of gas consumed. Two buttons should be placed on the form. Name all objects used in program statements. When the user clicks a button that performs the calculation, display in a label the miles per gallon for that trip. The second button should be used to reset or clear textbox entries.
