[Solved] Understanding stringstream [closed]

Question

There’s a constructor for std::stringstream that takes a std::string as a parameter and initializes the stream with that value.

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

int main() {

    std::stringstream ss("foo bar");

    std::string str1, str2;
    ss >> str1 >> str2;

    std::cout << "str1: " << str1 << std::endl;
    std::cout << "str2: " << str2 << std::endl;

}

This code initializes a stringstream, ss, with the value "foo bar" and then reads it into two strings, str1 and str2, in the same way in which you would read from a file or std::cin.
