程序规范：
设计并实施一个程序，该程序将创建并使用三个 类型不同的变量。
使用typedef命令在DATE创建一个结构。
使用以下字段为PERSON创建结构。
姓名[这将是一个字符串]生日[这将是一个DATE]性别 [这将是一个字符] AnnualIncome [这将是浮动或 翻倍，由您选择]创建三个PERSON类型的变量。创建一个 该函数可填充每个人（全部3个人）的数据。 创建一个函数，以输出有关每个人的所有数据 很好的格式化方式。
数据验证：
所有输入的日期必须经过验证。确保您考虑了 每个月的天数，实际上恰好有12天 每个月都有一个four年。
每个人的姓名将以大写形式存储。
性别将是M，F或O。
年收入在0美元到100万美元之间。

所以我的程序运行得很稳定，但是由于result.month == 09（它检查是否只有一个30天的月份，第139行），所以我确实收到一条错误消息，指出八进制数字无效。如果有人以这种方式输入，我将9和09都包含个位数月份。直到我达到7以上，这才成为问题。如何解决这个问题，以允许将月份输入为9或09。当前，当有人输入09时，result.month的值为0或一些奇怪的数字，它不会阻止输入数字，并允许09的天数应该是31时才应该是30。希望这一点足够清楚，以便其他人理解，我尝试提供尽可能多的信息。感谢他们的帮助！
答案 0 :(得分：0)
0中的result.month == 09开始为八进制整数常量，而其余的（9）不是八进制。因此，编码错误。请改用result.month == 9。
将scanf_s("%i",...更改为scanf_s("%d",...以仅读取输入的小数。
可能存在其他问题。
