Membuat Aplikasi Rental CD dengan Borland C++

Beberapa hari lalu saya ada tugas dari kampus. Disuruh membuat program menggunakan Borlan C++ dengan kriteria sebagai berikut :

Harus terdapat Array
Harus terdapat Nested If
Harus terdapat Function
Harus terdapat Struct

Berkali-kali error ketika pembuatan, banyak waktu terbuang... anjrit ngeselin bangetkan. Syukur-syukur itu semua ada hikmahnya.

Langsung saja yah ke topik pembahasan.

Ini Source Code nya :

#include <conio>
#include <stdio>
#include <iostream>
#include <iomanip>
#define bersih() clrscr()

grs()
{cout<<"========================================"<<endl;}

main()
{
int i,a,total=0;
struct
{
long int harga,jml,jmlsw,lase;
char koge[20],genre[20],kodecd[20],namacd[20],lagi;
}rent[20];
struct
{
int bayar,kembali;
char tgl[18],customer[25];
}disk;

awal:
bersih();
cout<<" \t\tRENTAl CD DISC MUSIC"<<endl;
grs();
cout<<" Harga Sewa CD :"<<endl;
cout<<" ======================="<<endl;
