There is no << operator defined for an std::ostream and an std::vector<std::string>.
In other words, it doesn't know how to print a vector.
If you want to be fancy, you could implement your own << operator

#include <iostream>
#include <string>
#include <vector>
std::ostream& operator<<(std::ostream& os, const std::vector<std::string>& vec)
{
os << "{";
for (size_t i = 0; i < vec.size()-1; i++)
{
os << vec[i] << ", ";
}
os << vec.back() << "}";
return os;
}
int main()
{
std::vector<std::string> v {"tree", "banana", "password123"};
std::cout << v << std::endl;
}

Otherwise, just copy and modify lines 7-12 (change os to cout, etc.)
