Synopsis¶

Defined in header <regex>
template<class ForwardIt>

basic_regex(ForwardIt, ForwardIt,
std::regex_constants::syntax_option_type = (since C++17)
std::regex_constants::ECMAScript)

-> basic_regex<typename std::iterator_traits<ForwardIt>::value_type>;

This deduction guide is provided for std::basic_regex to allow deduction from an
iterator range.

Example¶

// Run this code

#include <regex>
#include <vector>
int main() {
std::vector<char> v = {'a', 'b', 'c'};
std::basic_regex re(v.begin(), v.end()); // uses explicit deduction guide
}
