I have never used stringstream before and was given a sample code but with no explanation of what was happening in the code. If someone could explain each line's purpose that would be great. I have looked in multiple places but cant seem to pin down the second line.
#include <sstream> // i know this line includes the file
stringstream ss(aStringVariable);// this line in particular
ss >> aVariable;
getline(ss, stringVariable2HoldValue, ‘|’);
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.
