Question

Please submit a screenshot of where your code got compiled, executed, showing the execution result

Write a program/function in python that will perform the following functions, when the program is executed, to demonstrate the features of an OOP language—ADT, inheritance, and polymorphism:

1. Prompt a list of options—the main menu, below to compute the area of selected shape with input parameters:
   1. triangle
   2. rectangle
   3. square
   4. circle
   5. parallelogram
   6. Exit
2. Per the selected option, prompt grader to enter the corresponding required parameters as described below:
   1. base and height
   2. length and width
   3. side
   4. radius
   5. base and height
3. Your program should validate the number of input parameter(s) and the parameter(s).
   1. If the number of parameter(s) is incorrect OR the parameter is invalid (e.g., 0 or -3), display the message—input parameter(s) is/are incorrect, and allow grader to re-enter the correct parameter(s)
   2. If the input parameter(s) is/are valid, display the computed area based on the input parameter(s), and then allow grader to go back to the main menu to select any one of options.
   3. Assuming the unit is ft for all input parameters.

Please DO NOT hard-code any input values, output values in your code.

Answer 1

Below is the answer:

def AreaCircle():

  Radius=0

  while(Radiius<=0):

    Radius = float(input('Enter the Circle Radius (>0) = '))

  A = 3.1457 * Radius * Radius

  return A

   

   

def AreaRectangle():

  Flag=1

  while(Flag):

    Flag=0

    Dim = (input('Enter the Length and Width = '))

    x = (Dim.split(' '))

    if(len(x)==2):

      if(float(x[0])==0 or float(x[1])==0): Flag=1

    else:

      Flag=1

  A = float(x[0])*float(x[1])

  return A



def AreaSquare():

  Side=0

  while(Side<=0):

    Side = float(input('Enter the Square Side (>0) = '))

  A = Side * Side

  return A



def AreaParallelogram():

  Flag=1

  while(Flag):

    Flag=0

    Dim = (input('Enter the Base and Height (>0) = '))

    x = (Dim.split(' '))

    if(len(x)==2):

      if(float(x[0])==0 or float(x[1])==0): Flag=1

    else: Flag=0   

  x = (Dim.split(' '))

  A = float(x[0])*float(x[1])

  return(A)



def IsValid(Side1,Side2,Side3):

  Flag=0;

  Sum = Side1 + Side2

  if(Sum>Side3 and Flag==0):

     Flag=1    



  Sum = Side2 + Side3

  if(Sum>Side1 and Flag==0):

     Flag=1    



  Sum = Side1 + Side3

  if(Sum>Side2 and Flag==0):

     Flag=1    

  return Flag



def Area(Side1,Side2,Side3):

   u = float(Side1)

   v = float(Side2)

   w = float(Side3)

    

   s = (u+v+w)/2

   A = math.sqrt(s*(s-u)*(s-v)*(s-w))

   return(A)

    







Command=6

Flag=1

while(Flag):

  Command=6

  while(Command<0 or Command>5):

    print("\nFor Triangle,  Press --> 1")

    print("For Rectangle,   Press --> 2")

    print("For Square,    Press --> 3")

    print("For Circle,    Press --> 4")

    print("For Parallelogram, Press --> 5")

    print("To QUIT,      Press --> 0")

    Command= int(input('Enter the Shape No. (1 to 5): '))

  Ar=0;

  if(Command == 0):

    Flag=0

  if(Command == 2):

    Ar = AreaRectangle();

    print("Area of Rectangle = %s"%Ar)

  if(Command == 3):

     Ar = AreaSquare();

     print("Area of Square = %s"%Ar)

  if(Command == 4):

     Ar = AreaCircle();

     print("Area of Circle = %s"%Ar)

  if(Command == 1):

    x=[]

    while(len(x)!=3):

      Sides= input('Enter three sides of a triangle followed by space: ')

      x = Sides.split()

    a = int(x[0])

    b = int(x[1])

    c = int(x[2])

    TriangleValidFlag = IsValid(a,b,c)

    if(TriangleValidFlag):

       print("TRUE: The sides are valid.")

       Ar = Area(a,b,c)

       print("Area = %s"%Ar)

    if(TriangleValidFlag==0):

       print("FALSE: The sides are not valid")

  if(Command == 5):

    Ar = AreaParallelogram();

    print("Area of parallelogram = %s"%Ar)
