Create a menu-driven program that calculates the area of a few, basic geometric shapes. The program begins by displaying the menu to the user. The user has four choices to select from:

1. Calculate the area of a circle.
2. Calculate the area of a rectangle.
3. Calculate the area of a triangle
4. Exit the program

After displaying the menu, the program gets the user's choice and performs the desired action. The program then starts over at the menu, allowing the user to choose again. The program stops when the user finally enters option 4.

Answer:

todo = True

[tex]print("Menu\n\ 1 - Area\ of\ Circle\n\ 2 - Area\ of\ Rectangle\n\ 3 - Area\ of Triangle\n\ 4 - Exit")[/tex]

menu = int(input("Select Menu: "))

while(todo):

   if menu == 1:

       radius = float(input("Radius: "))

       print("Area: "+str(3.142 * radius * radius))

       todo = True

       menu = int(input("Select Menu: "))

   elif menu == 2:

       length = float(input("Length: "))

       width = float(input("Width: "))

       print("Area: "+str(length * width))

       todo = True

       menu = int(input("Select Menu: "))

   elif menu == 3:

       bs = float(input("Base: "))

       hght = float(input("Height: "))

       print("Area: "+str(bs * hght/2))

       todo = True

       menu = int(input("Select Menu: "))

   elif menu == 4:

       todo = False

   else:

       print("Invalid menu selected")

       todo = True

       menu = int(input("Select Menu: "))

The current calendar, called the Gregorian calendar, was introduced in 1582. Every year divisible by four was declared to be a leap year, with the exception of the years ending in 00 (that is those divisible by 100) and not divisible by 400. For instance, the years 1600 and 2000 are leap years, but 1700, 1800, and 1900 are not. Write a program that requests a year as input and states whether it is a leap year. (Test the program on the years 2008, 2009, 1900, and 2000.)
