程序规格：
设计和实现一个程序，它将创建并使用PERSON类型的三个不同变量。
使用typedef命令为DATE创建结构。
使用以下字段为PERSON创建结构。
name [这将是一个字符串] birthdate [这将是一个DATE]性别[这将是一个char] annualIncome [这将是float或double，你的选择]创建三个PERSON类型的变量。创建一个为每个人（所有3个人）填充数据的函数。创建一个函数，以一种很好的格式化方式输出关于每个人的所有数据。
数据验证：
输入的所有日期必须经过验证。确保记录每个月的天数，事实上正好有12个月，每四年有一个闰年。
每个PERSON的名称将以句子形式存储。
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非常可靠，但是因为result.month == 09（它检查一个月只有30天，第139行），我收到一个错误，说无效的八进制数字。我把9和09的单个数字包括在内，以防人们以这种方式进行。直到我达到7以上它才成为一个问题。如何解决此问题以允许将月份输入为9或09.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，并且允许09的日期为31，当它应该只有30时。希望这对于某人理解是足够清楚的，并且我试图提供尽可能多的信息。谢谢他们的帮助！
0中的result.month == 09开始八进制整数常数，其余（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",...以仅读取十进制输入。
可能存在其他问题。
