Write a small program called window.cpp to calculate the cost of a rectangular window. The total cost of a window is based on two prices; the cost of the glass plus the cost of the metal frame around the glass. The glass is 50 cents per square inch (area) and the metal frame is 75 cents per inch (perimeter). The length and width of the window will be entered by the user.
