Question

Write an interactive C++ program that uses a function to calculate the volume of a ball. The following code has numerous mistakes. Fix the mistakes and add any missing statements to get a working program. Test cases: ----------- 1. radius of 5, should give 523.599 */
#include <iostream>
using namespace std;

int main()
{
   // 1. input the radius of the ball
   cout << "Enter the radius of the ball: ";
   cin << radius;
   
   // 2. call the function to compute the volume of the ball
   volume_ball(double radius);

   // 3. display the results, using the variables radius and volume
   cout << "The volume of a ball with radius "
   << radius
   << " is "
   << volume
   << " ";
   
   system("pause");   
   return 0;
}

//function is defined
char volume_ball(r);
{
   double a = 4 / 3 * PI * r * r * r;
   
   return volume_ball;
}

Explanation / Answer

#include <iostream>

using namespace std;

int main()

{

// 1. input the radius of the ball

cout << "Enter the radius of the ball: ";

// cin << radius; // Mistake 1

cin >> radius;

// 2. call the function to compute the volume of the ball

// volume_ball(double radius); // Mistake 2

double volume = volume_ball (radius);

// 3. display the results, using the variables radius and volume

cout << "The volume of a ball with radius "

<< radius

<< " is "

<< volume

// << " "; // Mistake 3

<< endl;

system("pause");   

return 0;

}

//function is defined

// char volume_ball(r); // Mistake 4

double volume_ball (double r)

{

// double a = 4 / 3 * PI * r * r * r; Mistake 5 - PI not defined

double a = 4/3 * 3.14 * r * r * r;

// return volume_ball; //Mistake 6 - volume_ball is not the variable

return a;

}
