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
