I am trying to parse a user-entered string and separate it at all the spaces, but I don't know how to change the parameters to accept user-entered strings, just what string is programmed in for the string already.

I did not create this code, but I am trying to modify it to work like I want it to, so don't ask me the how the whole thing works.


Here is the code I am working on:

//parser class--------------------------------------------
class parser
{
	std::string text;
public:
	static const int max_field_size=100;
	
	explicit parser(const char *s) : text(s) {}
	
	void tokenize(char *fields[], int nf, const char breaker=' ')
	{
		// parses internal string, breaking at instances of <breaker>
		// which are thrown away. Returns separated values as fields
		std::istringstream buffer(text);
		int f=0;
		while (f<nf)
		{
			buffer.getline(fields[f], max_field_size, breaker);
			++f;
		}
	}
};
//end of parser class--------------------------------------


int main()
{
	...
		cin >> string s;
	parsef(s);
	...
}

//string parsing Function----------------------------------
void parsef(string s)
{
	
	const char* userstring="RUN filename and this\n";
	char **fields = new char*[3];
	for (int i=0; i<3; ++i)
		fields[i]=new char[parser::max_field_size];
	
	parser parse(userstring);
	parse.tokenize(fields, 3);
	for (int i=0; i<3; ++i)
		cout << "word " << i << ": " << fields[i] << endl;
	
}
//end string parsing Function------------------------------

Only what I put in for 'userstring' is parsed. I don't know how to get the string I pass to the parse function to be the string parsed.

I thinking it's something simple to do, but I just can't figure it out.
Could someone help, please? And thanks.
