Rozwiązanie:
a)bez parametrów
#include <iostream>
using namespace std;
double r, h;
double objetosc()
{
return 3.14159 * r * r * h;
}
int main()
{
cout << "Obliczanie objetosci walca" << endl;
cout << "Podaj r: "; cin >> r;
cout << "Podaj h: "; cin >> h;
if (r > 0 && h > 0) cout << "Objetosc = " << objetosc();
else cout << "Zle dane!";
return 0;
}
b)z parametrami(r, h)
#include <iostream>
using namespace std;
double objetosc(double r, double h)
{
return 3.14159 * r * r * h;
}
int main()
{
double r, h;
cout << "Obliczanie objetosci walca" << endl;
cout << "Podaj r: "; cin >> r;
cout << "Podaj h: "; cin >> h;
if (r > 0 && h > 0) cout << "Objetosc = " << objetosc(r, h);
else cout << "Zle dane!";
return 0;
}
