c语言使用txt文档星座输入

问题遇到的现象和发生背景

做一个小程序来展示学生的基本信息，现在就想把星座也加进去，但是现在只做了统计，星座加入太麻烦，想问问有没有更便捷的方法。

用代码块功能插入代码，请勿粘贴截图

运行结果及报错内容

我想要达到的结果

想把星座加入到人名后面，通过新建一个函数加switch可以达到效果，但是太复杂，求一个简便一点的解答，谢谢

• 帮你找了个相似的问题, 你可以看下: https://ask.csdn.net/questions/7754716

往往越简单的逻辑越好，没有一定的基本功和算法能力不要去优化代码，就用你这样就很好很直观，而且效率也很高。
