Question

I have a std::string that contains comma separated values, i need to store those values in some suitable container e.g. array, vector or some other container. Is there any built in function through which i could do this? Or i need to write custom code for this?

If you’re willing and able to use the Boost libraries, Boost Tokenizer would work really well for this task.

That would look like:

std::string str = "some,comma,separated,words";
typedef boost::tokenizer<boost::char_separator<char> > tokenizer;
boost::char_separator<char> sep(",");
tokenizer tokens(str, sep);
std::vector<std::string> vec(tokens.begin(), tokens.end());
