Contoh script c++ menghitung durasi dan biaya billing warnet

#include <iostream.h>

#include <string.h>

#include <stdlib.h>

struct konsumen

{

  char nama [50];

  int h;

  int m;

  int s;

}

;

void main()

{

konsumen user ;

char buffer[10];

float durasi;

float biaya;

  cout << "input name   : ";

  cin.getline (user.nama,50);

  cout << "input hour   : ";

  cin.getline (buffer,6);

  user.h = atof (buffer);

  cout << "input minute : ";

  cin.getline (buffer,6);

  user.m = atof (buffer);

  cout << "input second : ";

  cin.getline (buffer,6);

  user.s = atof (buffer);

cout<<endl;

cout<<"Nama Konsumen : " << user.nama <<endl;

cout<<user.nama<<" telah menggunakan warnet selama "<<user.h<<" jam "<<user.m<<" menit "<<user.s<<" detik"<<endl;

durasi = ((user.h * 3600 )+ (user.m * 60 )+ (user.s));

biaya = ((durasi / 30) * 130);

cout<<user.nama <<" harus membayar sebesar Rp. "<< biaya;
