Answer 1

#include <iostream>
#include <algorithm>
#include <iterator>
#include <string>
#include <vector>

using std::cout;
using std::endl;
using std::string;
using std::vector;

int main()
{
	string s1("abcdefg");
	string s2("acddeij");

	vector<char> vec1(s1.begin(), s1.end());
	vector<char> vec2(s2.begin(), s2.end());

	vector<char> diff;

	set_symmetric_difference(vec1.begin(), vec1.end(), 
		                     vec2.begin(), vec2.end(), back_inserter(diff));

	std::copy(diff.begin(), diff.end(), std::ostream_iterator<char>(cout, " "));

	cout << endl;

	return 0;
