Program Menghitung Bilangan Kompleks

- Masalah :
 Menghitung bilangan kompleks
-Analisis :
 Input: bilangan asli.
 Output: bilangan kompleks.

-C++ :
#include<iostream>
#include <stdlib.h>
#include <conio.h>
using namespace std;
struct 
{
float r1;
float r2;
float i1;
float i2;
}bilangan;
int main(int argc, char** argv)
{ 
 cout<<"\n____________________________";
 cout<<"\n| OPERASI BILANGAN KOMPLEK |";
 cout<<"\n____________________________\n";
 cout<<"bilangan real 1 = "; cin>>bilangan.r1;
 cout<<"bilangan imajiner 1 = "; cin>>bilangan.i1;
 cout<<endl<<endl;
 cout<<"bilangan real 2 = "; cin>>bilangan.r2;
 cout<<"bilangan imajiner 2 = "; cin>>bilangan.i2;
 cout<<endl<<endl;
