Answer 1

using namespace std;

#include <iostream>

#include <math.h>

//answer and radius-squared passed by address for whatever reason

double ComputeVolume(double r, double h, double * ans, double * r2);

int main(int argc, char** argv)

{

double radius,height,ans,r2;

cout << "Please input the radius :>";

cin >> radius;

cout << "Please input the height :>";

cin >> height;

ans = ComputeVolume(radius,height,&ans,&r2);

cout << "Volume :" << ans << endl;

return 0;

}

double ComputeVolume(double r, double h, double * ans, double * r2)

{

*r2 = r*r;

*ans = (1.0f/3) * M_PI * *r2 * h;

return(*ans);

}
