首先,我们需要定义一个正则表达式模式,该模式使用"\s"来匹配空格字符。然后,我们使用该模式实例化一个sregex_token_iterator对象,并将字符串的开始和结束位置作为参数传递。 接下来,我们在while循环中迭代遍历sregex_token_iterator对象,直到遍历完所有的子字符串。在每次迭代中,我们打印出当前迭代器指向的子字符串,...

正则表达式基本语法与C++相同,参照C++,具体使用参照test.c 不同的是在C语言的版本中没有sregex_token_iterator类,所以直接给出了regex_splite函数,分割后的 字符串存放于regex结构体中,具体情况可以看test.c示例代码 C语言的版本中不仅在regex->token_strs中得到分割的字符串, 还可以在regex->match_strs中得到...

It's only 228 bytes before that big round number. Now that could be the base address of some dll (unlikely) or it could be a memory mapped file or device of some kind (more likely to get a round number this way than through the heap). And 228 bytes sounds suspiciously like the ...

boost::sregex_iterator()和boost::cregex_token_iterator()是Boost库中用于正则表达式处理的迭代器,它们可以帮助我们在字符串中查找或分解出与指定的正则表达式模式匹配的子字符串序列。 sregex_iterator 迭代查找一个输入字符串中符合给定正则表达式模式的所有匹配字符串序列。
