C程序结构分配无效的八进制数字

Question

程序规格：

设计和实现一个程序，该程序将创建并使用PERSON类型的三个不同变量。

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。

名称[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float或double，您可以选择]创建三个PERSON类型的变量。 创建一个函数来填充每个人（所有3个人）的数据。 创建一个函数，该函数以一种很好的格式化方式输出有关每个人的所有数据。

数据验证：

输入的所有日期都必须经过验证。 确保计算每个月的天数，即恰好有12个月，每四年有is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美元至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，指出无效的八进制数字。 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！

Answer 1

result.month == 09的0开始一个八进制整数常量，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",...以仅读取十进制输入。

可能存在其他问题。
