Membuat Database

Hai Kawan! Ketemu lagi dengan Bang Fathur disini Kali ini kita akan membuat database yang lumayan ribet codingannya tapi untuk kalian jangan mudah menyerah dan terus berusaha. Langsung aja inilah codingnannya bisa kalian lihat dan copas dibawah ini

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<conio.h>
main()
{
        int pilih1, pilih2, pilih3;
        FILE *pf;
        int data, i,harga ;
        char nama[40];
        char kar, again='y';
      
        do{
                printf("\n===========================================\n\t\tKAMPUS IBMB\n-------------------------------------------\n");
                printf("\n1. Menginput dengan Menghapus data sebelumnya\n");
                printf("\n2. Menambahkan Data tanpa Menghapus\n");
                printf("\n3. Melihat Data Keseluruhan\n");
                printf("\n-------------------------------------------\n");
                printf("pilihan Anda ?");
                scanf("%d",&pilih1);
                printf("\n===========================================\n");
                if(pilih1>3){
                        printf("INPUT SALAH, COBA LAGI!!\n");}
                switch(pilih1)
        {
        case 1:
                {
                        if((pf=fopen("latihan.txt","w"))== NULL)
                        {
                                printf("file gagal diciptakan!\n");
                                exit(1);
                        }
                        printf("Masukkan banyaknya barang :");
                        scanf("%d",&data);
                        for(i=1;i<=data;i++)
                        {
                                printf("\nBarang ke %d : ",i);fflush(stdin);
                                gets(nama);
                                strcat(nama,"\n");
                                fputs(nama, pf);              
                        }
                        printf("============================\n");
                        printf("Oke. Data sudah disimpan !!\n");
                        printf("============================\n");
                        fclose(pf);
                } 
                printf("Kembali ke menu [y/t] ? ");
        again=getch();
        break;
        case 2:
                {
                        if((pf=fopen("latihan.txt","a"))== NULL)
                        {
                                printf("file gagal diciptakan!\n");
                                exit(1);
                        }
                        printf("Masukkan banyaknya Barang :");
                        scanf("%d",&data);
                        for(i=1;i<=data;i++)
                        {
                                printf("\nBarang ke %d : ",i);fflush(stdin);
                                gets(nama);
                                strcat(nama,"\n");
                                fputs(nama, pf);              
                        }
                        printf("============================\n");
                        printf("Oke. Data sudah disimpan !!\n");
                        printf("============================\n");
                        fclose(pf);
                }
                printf("Kembali ke menu [y/t] ? ");
        again=getch();
        break;
      
        case 3:
                {
                        if ((pf=fopen("latihan.txt","r"))== NULL)
                        {
                                printf("file tak dapat dibuka !\r\n");
                                exit(1);
                        }
                        while((kar=fgetc(pf)) !=EOF)
                        putchar(kar);
                        printf("\n");
                        fclose(pf);
                }
        printf("Kembali ke menu [y/t] ? ");
        again=getch();
    break;
        }
  }while(again=='y'); 
}

Dan setelah di compile akan muncul tampilan seperti ini

Selamat Mencoba Guys!!
