我目前正在研究其他杂项剧场座位计划!我刚刚开始通过C++进行开发，但是我无法弄清楚这些错误。我试图使程序在两个 vector 中存储用户输入的行号和行席位(仅在有多个席位的情况下)； vector seat_row()和 vector seat_number()。我知道错误说明了什么，但是我不知道如何处理这种情况。抱歉，如果我不太清楚，但是老实说，我不知道还包括什么。请看一下我的代码，感受一下我的程序，让我有什么想法。请保持答案有些简单；再次，我不是C++的高手
附言
很抱歉显示完整的代码。。。我真的不知道要包括什么，不包括什么。我希望人们甚至可以自己测试一下就可以对程序有感觉……再次感谢!
