// saran
// 1. biar ga pusing pake var global aja guna menghindari pass by reff/pass by value
// 2. kalo mau enak menu utama jangan di int main tapi di function tersendiri(contoh di atas void home)
// 3. kalo mau baca string yg terpisah scanf("%[^\n]",blabla) ga usah pake %s
// 4. cara baca data dari file @makan#minum itu "@%[^#]#\n" pake @ didepan berati baru dibaca setelah lambang @ pake \n buat baca data di line berikutnya
// 5. untuk memudahkan sort yg bermacam-macam bisa buat function sendiri dalam contoh "void trade(int a)"
// kalo ada pertanyaan bisa tanya gw kalo mau ^_^ SUKSES YAAA 01 PRT ALGONYA
