Question

i write this program to split string in QtCreator

#include <QtCore/QCoreApplication>
#include <iostream>
#include <istream>
using namespace std;



int main()
{
string s("Somewhere down the road");
istringstream iss(s);

do
{
    string sub;
    iss >> sub;
    cout << "Substring: " << sub << endl;
} while (iss);

return 0;
}

but it returns this error

main.cpp:23:24: error: variable ‘std::istringstream iss’ has initializer but incomplete type

why? what have i do ?
is there any other easy ways ?

thanks

You need to include the <sstream> header for string streams.
