简单的旅游景点售票系统C语言代码

以下是一个简单的旅游景点售票系统C语言代码，可以作为参考：

#include <stdio.h>

int main() {
  int choice, quantity, price, total_price;
  printf("Welcome to the Travel Agency!\n");
  printf("Please choose a destination:\n");
  printf("1. Beijing - $100 per ticket\n");
  printf("2. Shanghai - $80 per ticket\n");
  printf("3. Guangzhou - $50 per ticket\n");
  printf("4. Shenzhen - $60 per ticket\n");
  printf("Enter your choice (1-4): ");
  scanf("%d", &choice);
  
  switch (choice) {
    case 1:
      price = 100;
      printf("You selected Beijing. The ticket price is $%d.\n", price);
      break;
    case 2:
      price = 80;
      printf("You selected Shanghai. The ticket price is $%d.\n", price);
      break;
    case 3:
      price = 50;
      printf("You selected Guangzhou. The ticket price is $%d.\n", price);
      break;
    case 4:
      price = 60;
      printf("You selected Shenzhen. The ticket price is $%d.\n", price);
      break;
    default:
      printf("Invalid choice.\n");
      return 0;
  }
  
  printf("How many tickets do you want to buy? ");
  scanf("%d", &quantity);
  
  total_price = price * quantity;
  printf("You selected %d tickets. The total price is $%d.\n", quantity, total_price);
  
  printf("Thank you for choosing the Travel Agency!\n");
  
  return 0;
}

以上代码实现了一个简单的旅游景点售票系统，用户可以选择想要购买的目的地和数量，程序会计算出总价并输出。
