C++, Boost regex, replace value function of matched value?
Specifically, I have an array of strings called val, and want to replace all instances of "%{n}%" in the input with val[n].

I found some .NET (C#...

Boost regexp - null-termination of search results
boost::regex re; re = "(\\d+)"; boost::cmatch matches; if (boost::regex_search("hello 123 world", matches, re)) { printf("Found %s\n", matches[1]); } Result: "Found 123 world". I just wanted the "123". Is this some problem with null-termination, or just misunderstanding how regex_search works? ...

Boost regex and confusing errors
I'm trying to use Boost regex to see if something has an integer in it. One of the examples on this page is bool validate_card_format(const std::string& s) { static const boost::regex e("(\\d{4}[- ]){3}\\d{4}"); return regex_match(s, e); } There's also a presumably working example here. But when I try it on my machine, I get f...
