Write a program with overloaded prototypes of volume(), a function that returns volumes of different structures . Write 3 versions : one for cube's volume that takes one float side of the cube, one for cylinder's volume that takes float radius and float height of the cylinder, and one rectangular box's volume that takes float length, float breadth and float height of the box.

A function name having several definitions that are differentiable by the number or types of their arguments(signature), is known as function overloading.

#include<iostream.h>

#include<conio.h>

// Volume of a cube

double volume(float s)
{
double vol;
vol = (double) ( s * s * s);
return vol ;}


// volume of a cylinder
double volume(float r, float h)
{
double vol = (double)(3.14 * r * r * h);
return vol;
}

// volume of a rectangular box
double volume( float l, float b, float h)


{
double vol = (double) (l * b * h );
return vol;
}

void main()

{

double volume(float s);

double volume(float r, float h);

double volume ( float l, float b, float h);

/* Volume of a cube with side 3.6 unit */

double v = volume(3.6);

cout<< "\n The Volume of a cube = " << v << "Unit Cube";

/* Volume of a cylinder with radius 2.5 unit, height = 6 unit */

v = volume(2.5, 6);

cout<< "\n The Volume of a cylinder = " << v << "Unit Cube";

/* Volume of a rectangular box of l = 10, b =6 , h =4 units , respectively */

v = volume(10, 6, 4);

cout<< "\n The Volume of a rectangular box = " << v << "Unit Cube";
