Program C++ Fungsi Menghitung Volume Bola

Algoritma :

Deskripsi

r                 : integer

volume           : float

Deklarasi

volume <= 4/3*3.14*r*r*r

write (volume)

Berikut programnya :

#include<iostream.h>

#include<conio.h>

void bola()

{

  int r,volume;

  cout<<"masukan nilai jari-jari : ";

  cin>>r;

  cout<<"volume bola = "<<4/3*3.14*r*r*r<<endl;

}

int main() {

    bola();

    return 0;

}

Program classnya:

#include <iostream.h>

#include <conio.h>

class volume {

friend istream& operator >> (istream&, volume&);

friend ostream& operator << (ostream&, const volume&);

public:

volume();

void hitung_volumenya(){ volume = 4/3*3.14*r*r*r;}

private:

    int r;

    float volume;

};

volume::volume(){

cout << "Program mencari volume bola \n" << endl;

}

istream& operator >>(istream& cin, volume& masukan){

   cout << "Masukkan jari-jari : ";   cin >> masukan.r;

   cout<<endl;

return cin;

}

ostream& operator << (ostream& out, const volume& keluaran)

{

  out<< " Nilai jari- jari : " <<keluaran.r<<endl;

  out<< " volume bola = "<<keluaran.volume<<endl;

return out;

}

void main(){

  volume bola;

  cin>>bola;

  bola.hitung_volumenya();

  cout<<bola;

  getch();

}

Demo ke jeliot :

Fungsi Menghitung Volume Bola

import jeliot.io.*;

public class volume {

public static void main()

{

     int r ;

     float volume;

     System.out.print("Masukan jari-jari : ");

     r = Input.readInt();

    

     volume = (float)4/3*(float)3.14*r*r*r;

     System.out.print("Volume bola = ");

     System.out.print(volume);

 }

}

Explanation:
The above program is a program to calculate the volume of the ball by using the function. Which program would invoke the functionality. In this program using a variable r and the volume. The program will do the counting process with a predetermined formula. After users input the value of r then the volume of the ball will appear.
