字符串处理常用的一个操作是「匹配」,即字符串和规则恰好对应,而用于匹配的函数为std::regex_match,它是个函数模板,我们直接来看例子: 1std::regexreg("<.*>.*</.*>"); 2boolret =std::regex_match("value", reg); 3assert(ret); 4 5ret =std:...
Looking at the standard library documentation I found that when using the ECMAScipt 'regular expression language' that one could also pass the flag "regex_constants::multiline" to the regex constructor. I tried to see what difference this would make, but found that the regex_constants::multi...
