confirm that the result of stringstream is integer.

How can i ensure that 1024 is an integer? thank you....

Code:

---

#include <iostream>
#include <string>
#include <sstream>

using namespace std;

int main(void){
        int age;
        string buf("1024");
                stringstream(buf) >> age;
                cout << age << ".\n";
       
return 0;
}

Check the state of the stream after the extraction. Typical method:

Code:

---

std::stringstream sstr(buf);
if (sstr >> age) // Extraction OK
if (!(sstr >> age)) // Extraction not OK
