Question #261 Difficulty:
According to the C++17 standard, what is the output of this program?
#include <iostream>
#include <sstream>
int main() {
std::stringstream ss("a");
std::cout << ss.str();
ss << "b";
std::cout << ss.str();
}
Hint:
The default open mode in the constructor does not set std::ios_base::ate
, so where in the buffer will the next character be written when we call operator<<
?

I give up, show me the answer (make 3 more attempts first).
