Question

Write a program to find out volume of the following using function overloading.

• volume of cube
• volume of cuboid
• volume of cylinder

Answer 1

Python simulates function overloading here with optional parameters: one argument is for a cube, two arguments are for a cylinder, and three arguments are for a cuboid.

def volume(a, b=None, c=None):
    if b is None and c is None:
        # Volume of cube
        return a * a * a

    elif c is None:
        # Volume of cylinder
        return 3.14 * a * a * b

    else:
        # Volume of cuboid
        return a * b * c


# Cube
s = float(input("Enter side of cube: "))
print("Volume of cube =", volume(s))

# Cuboid
l = float(input("Enter length of cuboid: "))
b = float(input("Enter breadth of cuboid: "))
h = float(input("Enter height of cuboid: "))
print("Volume of cuboid =", volume(l, b, h))

# Cylinder
r = float(input("Enter radius of cylinder: "))
h = float(input("Enter height of cylinder: "))
print("Volume of cylinder =", volume(r, h))
