How to split a string in C++?

Best way to split a string in C++? The string can be assumed to be composed of words separated by ;

From our guide lines point of view C string functions are not allowed and also Boost is also not allowed to use because of security conecerns open source is not allowed.

The best solution I have right now is:

string str("denmark;sweden;india;us");

Above str should be stored in vector as strings. how can we achieve this?

Thanks for inputs.

I find std::getline() is often the simplest. The optional delimiter parameter means it's not just for reading "lines":

#include <sstream> #include <iostream> #include <vector>  using namespace std;  int main() {     vector<string> strings;     istringstream f("denmark;sweden;india;us");     string s;         while (getline(f, s, ';')) {         cout << s << endl;         strings.push_back(s);     } }
