Question #261 Difficulty: 1

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<<?
