- sregex_token_iterator是一个前向迭代器,可以使用++it来移动迭代器。但不支持逆向迭代,也不支持随机访问。 总结: sregex_token_iterator函数是C++中处理正则表达式的强大工具,它可将字符串根据正则表达式模式进行拆分,并生成对应的匹配和非匹配子字符串。通过使用这个函数,我们可以有效地进行文本处理和字符串分割操作...
1. sregex_token_iterator( BidirIt first, BidirIt last, const regex_type& re, int submatch = 0 ); 该构造函数接受四个参数:迭代器的开始和结束位置、一个正则表达式对象和一个整数值用于指定需要提取的子串下标。该构造函数会将字符串按照正则表达式模式分割,并提取指定下标的子串。 2. sregex_token_ite...
