[RESOLVED] Problem with ostreamstring and setfill(): size() of the resulting string is one more.

Hi,

The s1.size() actually returns 4, and test for equality fails. I am using g++ on Linux, debug target.

Could someone help. Thank you.

#include <iostream>
#include <iomanip>
#include <sstream>

int main()
{
        int i = 8;
        std::ostringstream ss;
        ss << std::setw(3) << std::setfill('0') << i << "\n";
        std::string s1(ss.str());
        std::cout << s1 << " " << s1.size() << std::endl;
        std::string s2 = "008";
        std::cout << s2 << " " << s2.size() << std::endl;
        
        if (s1 == s2)
                std::cout << "equal" << std::endl;
        else
                std::cout << "not equal" << std::endl;
                        
        return 0;
}

ss << std::setw(3) << std::setfill('0') << i << "\n";

'\n' is part of ss!
