我想知道如何验证以逗号分隔的字符串
C1，2，12344，Mr，John， ; Chan，05/07/1976" .........
我需要根据一组规则验证每个字段值，例如
检查字符串是字符还是数字值，对于字符的
长度等。
I want to know how to validate a string which is comma separated
"C1","2","12344","Mr","John","Chan","05/07/1976".........

分隔stri进入字段，然后将每个子字段
与验证标准进行比较。其余部分留给读者练习
。
Separate the string into the fields, and then compare each subfield
against the validation criteria. The remainder is left as an exercise
for the reader.
嗨红，
可以你更具体。因为我是c ++编程的新手。
如何将字符串分成字段？我如何验证
每个人？
如果你可以帮我解决一些示例程序或某些网站
用这个来帮助初学者会很有帮助。
谢谢，

Hi Red,
Can you be more specific. as i am a newbie to c++ programming.
How do I separate the string into the fields? and how do I validate
each of them?
If you can help me out with some example programmes or some websites
which help out begginners with this it will be quite help full.
Thanks,
Nishanth
