Problem with re-using a stringstream object

I'm trying to use safe practices in handling input with numbers only in C++, so I use a stringstream object as so: ``` #include <iostream> #include <string> #include <sstream> using namespace std; int main() { int first, second; string input; stringstream sstream; cout << "First integer: "; getline(cin, input); sstream.str(input); sstream >> first; cout << first << endl; //display user input in integers cout << "Second integer: "; getline(cin, input); sstream.str(input); sstream >> second; cout << second << endl; //display user input in integers getline(cin, input); //pause program return 0; } ``` However, the second time around it seems to give the variable 'second' an arbitrary value. This is the output: ``` First integer: 1 1 Second integer: 2 2293592 ``` If I declare two stringstream objects and use them respectively for both variables it seems to work fine. Does this mean that I cannot re-use a stringstream object in the way I'm trying to do? In my real program I intend to handle much more than two input values from the user, so I just want to make sure if there's another way instead of making multiple stringstream objects. I doubt it's of great relevance but I'm on Windows XP and I'm using MinGW as my compiler. I greatly appreciate any help.
