I'm a bit surprised C++ doesn't have an equivalent to Objective C's componentsSeparatedByString, but it's easy enough to roll your own, I suppose.

components_separated_by_string.cpp

#include <iostream>
#include <string>
#include <vector>

using namespace std;

vector<string>	components_separated_by_string( const string& s, const string& delimiter )
{
	if( s.size() == 0 )
		return vector<string>();
	
	size_t last = 0;
	size_t next = 0;
	vector<string>	components;
	while ((next = s.find(delimiter, last)) != string::npos)
	{
		components.push_back( s.substr(last, next-last) );
		last = next + 1;
	}
	components.push_back( s.substr(last) );
	
	return components;
}


int main(int argc, char *argv[])
{
	vector<string>	components = components_separated_by_string("Blue,Meanies,Rule,The,eWorld",",");

	for( string currStr : components )
		cout << currStr << endl;
}
