字符串拆分plzzzzzz帮我... [英] string splitting plzzzzzz help me...
问题描述
我有一个字符串
16：23：18.659343 131.188.37.230.22 131.188.37.59.1398 tcp 168
例如让我们说以上字符串
16：23：18.659343 - 时间
131.188.37.230 - srcaddress
22 --srcport
131.188.37.59 --destaddress
1398 --destport
tcp --protocol
168 --size
i需要拆分字符串，以便我需要获得所有这些
参数....
字段宽度不固定..我有一些四次/三位数
srcport ..所以我不能用substr函数做...我需要这个用c ++
i我不知道怎么拆分它..
感谢您的帮助
I have a string
16:23:18.659343 131.188.37.230.22 131.188.37.59.1398 tcp 168
for example lets say for the above string
16:23:18.659343 -- time
131.188.37.230 -- srcaddress
22 --srcport
131.188.37.59 --destaddress
1398 --destport
tcp --protocol
168 --size
i need to split the string such that i need to get all these
parameters....
the field widths are not fixed..i have some times four/three digits
srcport ..so i cant do it with substr function...i need this in c++
i am not getting an idea how to split it..
thank you for any help

线索是''。''所以根据每个
字段读取你想要的功能...
the clue is ''.'' so read function as many you want according to each
field...

你可以从拆分空格开始。然后确定
分割标记中的哪一个是ipv4地址（你关心ipv6吗？）和
strrchr（str，''。''）
解决方案似乎很容易。我建议你在开始编写网络代码之前回去学习
基础知识。
You could start by splitting the spaces. Then determine which from the
splitted tokens are ipv4 addresses (do you care about ipv6?) and
strrchr(str, ''.'')
The solution seems very easy. I suggest you go back to learning the
basics before you start writing networking code.
