TODO: std::queue and std::stack.
The function std::string string_ext::to_string(const T&) returns a string, which is the content of the parameter T.
T could be:
- std::pair
- std::tuple
- all kinds of STL containers
The types of elements inside of T must be streamable.
C++14 or higher is necessary.
int main() {
std::map<std::string, std::set<int>> mp {{"abc", {1, 2}}, {"def", {3, 4, 5}}};
std::cout << string_ext::to_string(mp) << std::endl;
std::array<int, 3> arr {1, 2, 3};
std::cout << string_ext::to_string(arr) << std::endl;
std::vector<std::pair<int, int>> vec{{1, 2}, {3, 4}};
std::cout << string_ext::to_string(vec) << std::endl;
std::tuple<int, int, int> tp {1, 2, 3};
std::cout << string_ext::to_string(tp) << std::endl;
return 0;
