An array can easily be converted into a std::vector by using std::begin and std::end:
int values[5] = { 1, 2, 3, 4, 5 }; // source array
std::vector<int> v(std::begin(values), std::end(values)); // copy array to new vector
for (auto &x: v) {
std::cout << x << " ";
}
std::cout << std::endl;1 2 3 4 5
int main(int argc, char* argv[]) {
// convert main arguments into a vector of strings.
std::vector<std::string> args(argv, argv + argc);
}A C++11 initializer_list<> can also be used to initialize the vector at once
initializer_list<int> arr = { 1,2,3,4,5 };
vector<int> vec1 {arr};
for (auto & i : vec1) {
cout << i << endl;
}
