C++ Program "Bangun Datar" by Sebastian Mandai

hallo....

kawan - kawan blogger semua ...dan juga para pecinta dunia IT. Postingan saya sebelumnya membahas tentang Apa Itu Bahasa Pemograman C++???, bagi teman - teman sekalian jika hanya membaca dan tidak mempraktekannya maka rasanya kurang malahan kita jadi tidak paham dengan apa yang dipelajari.

jadi, aku sedikiti berbagi nih, contoh Program C++ :

#include "iostream.h"
#include "conio.h"
 void main ()
{
 clrscr ();
 cout << "   Bangun Datar "<< endl ;
 cout << "=================== " << endl << endl ;
 const float PHI = 3.14 ;
 const float S   = 0.5 ;
 int s, t, l, p, d1, d2, r, a ;
 int luas_1, kllg_1, luas_2, kllg_2;
 float  luas_3, kllg_3, luas_4, kllg_4, luas_5, kllg_5 ;

 s  = 4 ;                  // s adalah sisi
 t  = 6 ;                  // t adalah tinggi
 l  = 2 ;                  // l adalah lebar
 p  = 3 ;                  // p adalah pangjang
 d1 = 12 ;                 // d1 adalah diagonal pertama
 d2 = 6 ;                  // d2 adalah diagonal kedua
 r  = 7 ;                  // r adalah jari - jari
 a  = 4 ;                  // a adalah alas

 luas_1 = s * s ;          // luas persegi
 kllg_1 = 4 * s ;          // keliling persegi

 luas_2 = p * l ;            // luas persegi panjang
 kllg_2 = 2 * (p + l) ;      // keliling persegi panjang

 luas_3 = S * a * t ;    // Luas Segitiga
 kllg_3 = s + s + s ;    // Keliling segitiga

 luas_4 = S * d1 * d2 ;    // Luas layang-layang
 kllg_4 = s + s + s + s ;  // Keliling layang - layang

 luas_5 = PHI * r * r ;     // Luas Lingkaran
 kllg_5 = 2 * PHI * r ;     // Keliling Lingkaran

 
 cout << "            |Persegi| " << endl ;
 cout << "            --------- " << endl ;
 cout << "|Sisi     =          " << "4" << "      |" << endl ;
 cout << "|Luas     =          " << luas_1 << "     |" << endl ;
