IOSTREAM, STRING & IOMANIP

Contoh 1 :
#include "iostream"
#include "string"
#include "iomanip"
using namespace std;
void main (){
int i=0;
char lagi='Y';
string nama [10];
long int harga [10];
cout<<"===== DATA PEMBELIAN ====="<<endl;
while (lagi=='Y') { //ulang selama ada barang
    cout<<"  NAMA BARANG  : ";cin>>nama[i];
    cout<<"  HARGA BARANG : ";cin>>harga[i];
    cout<<"====================\n";
    cout<<" ADA BARANG LAGI (Y/T) : ";cin>>lagi;
    cout<<"====================\n";
    i++; //kenaikan indeks array i
}
//cetak seluruh data pembelian;
system ("cls");
    cout<<"====================\n";
    cout<<" NO  ||  Nama   ||     Harga \n";
    cout<<"====================\n";
    for (int j=0;j<i;j++)
        cout<<setw(2)<<j<<setw(10)<<nama[j]<<setw(10)<<harga[j]<<endl;
    cout<<"====================\n";

system ("pause");
}

Contoh 2 :
#include "iostream"
#include "string"
#include "iomanip"
using namespace std;
void main (){
int i=0;
float total=0;
char lagi='Y';
string nama [10];
long int harga [10];
cout<<"===== DATA PEMBELIAN ====="<<endl;
while (lagi=='Y') { //ulang selama ada barang
    cout<<"  NAMA BARANG  : ";cin>>nama[i];
    cout<<"  HARGA BARANG : ";cin>>harga[i];
    cout<<"====================\n";
    cout<<" ADA BARANG LAGI (Y/T) : ";cin>>lagi;
    cout<<"====================\n";
    i++; //kenaikan indeks array i
}
//cetak seluruh data pembelian;
system ("cls");
    cout<<"=================================\n";
    cout<<" NO  ||  Nama   ||     Harga \n";
    cout<<"=================================\n";
    for (int j=0;j<i;j++){
    cout<<setw(2)<<j+1<<setw(10)<<nama[j]<<setw(15)<<harga[j]<<endl;
    total=total+harga[j];
    }
    cout<<"=================================\n";
    cout<<"               Total Harga : "<<total<<endl;
    cout<<"=================================\n";
system ("pause");
}
