#include <iostream>

struct book {
  std::string name, custormer;
  int days;
  long long int id;
  std::string type;
};

struct book library[100];

void rent_a_book();

void calc_total_amount();

int main()
{
  while ( true ) 
  {
    std::cout << "Rent a Book" << std::endl;
    std::cout << "Calculate total amount of all currency Rented Books" << std::endl;
    std::cout << "Exit the program" << std::endl;
    int n;
    std::cin >> n;
    switch ( n ) {
      case 1:
        rent_a_book();
        break;
      case 2:
        calc_total_amount();
        break;
      case 3:
        std::cout << "Exit the system" << std::endl();
        break;
      default:
        std::cout << "Oops.." << std::endl;
    }
  }
  return 0;
