Answer 1

Write a menu driven program using functions to calculate the volume of a cube,sphere and cylinder. Use separate functions

Explanation:

#include<iostream>

  using namespace std;

float vol(float);

 int vol(int);

  float vol(int,int);

  

    

  int main(  )

  {

   int r,h,a;

   float r1;

cout << “Menu” <<endl;

cout << “1-->Volume of Cylinder” <<endl;

cout << “2-->Volume of Cube” <<endl;

cout << “3-->Volume of Sphere” <<endl;

cout << “Enter the operation you want: ” <<endl;

cin>>choice;

switch(choice)

{

 case 1:

        cout<<"Enter radius and height of the cylinder to calculate volume:";

   cin>>r>>h;

   cout<<"Volume of cylinder is"<<vol(&r,&h);

break;

case 2:

   cout<<"Enter the side to calculate volume of a cube:";

   cin>>a;

   cout<<"\nVolume of cube is"<<vol(&a);

break;

case 3:

       cout<<"Enter the radius of sphere to calculate its volume:";

           cin>>r1;

      cout<<"\nVolume of sphere is"<<vol(r1);

}

      return 0;

  }

  float volofCylinder(int *r,int *h)

  {

      return(3.14*(*r)*(*r)*(*h));

  }

  float volofCube(float * r1)

  {

      return((4*3.14*(*r1)*(*r1)*(*r1)/3);

  }

  int volofSphere(int a)

  {

      return(a*a*a);

  }
