天气预测应用 weather项目

天气预测应用是一个基于C语言编写的控制台应用程序，允许用户查询特定城市的实时天气、未来天气、生活指数、PM2.5等信息。用户可以通过选择不同的功能键来获取所需的天气数据，并进行相关操作。选择城市：用户可以输入城市名称，应用会根据输入的城市名称获取相应的天气数据。实时天气：获取并显示当前城市的实时天气信息。未来天气：获取并显示当前城市的未来几天的天气预报。生活指数：获取并显示当前城市的生活指数，如紫外线强度、舒适度等。PM2.5 AQI：获取并显示当前城市的PM2.5和空气质量指数（AQI）。天气集合：同时获取当前城市的实时天气、未来天气、生活指数和未来小时天气数据。刷新：清屏并重新显示菜单。退出：退出应用程序。启动应用程序：显示主菜单，等待用户选择操作。选择城市：用户选择“选择城市”选项（输入1），并输入城市名称。程序会根据输入的城市名称保存用户的选择。获取天气数据：用户根据需求选择不同的天气数据选项：实时天气 (2)未来天气 (3)生活指数 (4)PM2.5 AQI (5)天气集合 (6)程序根据选择构建对应的HTTP请求
