Program Sederhana Dengan C++

Program Untuk Menghitung Luas dan Keliling Lingkaran:

Coding :

#include<iostream.h>

#include<conio.h>

#include<iomanip.h>

void main ()

{

 clrscr;

float jari ,keliling ,luas;

const float pi= 3.14;

cout<<"==========================================================\n";

cout<<"|  Program untuk menghitung LUAS dan KELILING LINGKARAN  |\n";

cout<<"==========================================================\n";

cout<<"Masukan panjang jari_jari(r) : ";cin>>jari;

luas = pi * jari * jari;  //rumus Luas lingkaran

keliling = 2 * pi * jari;      //rumus keliling lingkaran

cout<<"\n";

cout<<"\n";

cout<<"===========================================================\n";

cout<<"Luas lingkaran adalah     : "<<luas <<"\n";

cout<<"Keliling lingkaran adalah : "<<keliling <<"\n";

cout<<"===========================================================\n";

cout<<"\n";

cout<<"\n";

cout<<"Tekan ENTER untuk KELUAR";

getch ();

}

Hasilnya seperti gambar dibawah ini :
