Belajar C++, Penjualan Barang Elektroniok

Ini adalah contoh Program C++ :

#include<iostream.h>

#include<conio.h>

#include<string.h>

#include<math.h>

#include<iomanip.h>

void main()

{

char kd;

char nm[30];

char *nama;

int dis;

char *jenis;

int jumlah,jn;

float harga=0;

long Total;

long Tot;

char lagi='Y';

clrscr();

while(lagi=='Y' ||lagi=='y')

{

gotoxy(10,5);

cout<<"Penjualan Barang Elektronik\n";

gotoxy(10,6);

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

gotoxy(10,7);

cout<<"Nama Pembeli      = ";cin>> nm;

gotoxy(10,8);

cout<<"Kode Barang[A/B/C] = ";cin>> kd;

gotoxy(10,9);

cout<<"Jenis Bayar[1.Tunai/2.Kredit]  = ";cin>>jn;

gotoxy(10,10);

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

if ((kd=='A' || kd=='a') && (jn==1))

{

nama="Televisi";

jenis="Tunai";

harga=500000;

dis=0.05*500000;

}

else if ((kd=='A' || kd=='a') && (jn==2))

{

nama="Televisi";

jenis="Kredit";

harga=650000;

dis=0;

}

else if ((kd=='B' || kd=='b') && (jn==1))

{

nama="Kipas Angin";

jenis="Tunai";

harga=150000;

dis=0.07*150000;

}

else if ((kd=='B' || kd=='b') && (jn==2))

{

nama="Kipas Angin";

jenis="Kredit";

harga=250000;

dis=0;

}

else if ((kd=='C' || kd=='c') && (jn==1))

{

nama="VCD";

jenis="Tunai";

harga=300000;

dis=0.01*300000;

}

else if ((kd=='C' || kd=='a') && (jn==2))

{

nama="VCD";

jenis="kredit";

harga=450000;

dis=0;

}

else

{

nama="Tidak Ada";

jenis="Tidak Ada";

harga=0;

}

gotoxy(10,11);

cout<<"Nama barang     ="<<nama;

gotoxy(10,12);

cout<<"Jenis Bayar     = "<<jenis;

gotoxy(10,13);

cout<<"Harga Barang     = "<<setw(8)<<harga;

gotoxy(10,14);

cout<<"Jumlah Beli    = ";cin>>jumlah;

Total=harga*jumlah;

gotoxy(10,15);

cout<<"Total bayar    = "<<Total;

gotoxy(10,16);

cout<<"Diskon    = "<<dis;

gotoxy(10,17);

Tot=Total-dis;

gotoxy(10,18);

cout<<"Total  ="<<Tot;

gotoxy(10,19);

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

gotoxy(10,20);

cout<<"Masih Mau Beli Barang Lagi[Y/T]    = ";cin>> lagi;

clrscr();

}

}
