Question : array initialization
Answered by : anirban-mitra
The array will be initialized to 0 if we provide the empty initializer list or just specify 0 in the initializer list.
int arr[5] = {}; // results in [0, 0, 0, 0, 0]
int arr[5] = { 0 }; // results in [0, 0, 0, 0, 0]

std::array<std::string, 2> a3 = { std::string("a"), "b" };
// container operations are supported std::sort(a1.begin(), a1.end()); std::reverse_copy(a2.begin(), a2.end(), std::ostream_iterator<int>(std::cout, " "));
std::cout << '\n';
// ranged for loop is supported for(const auto& s: a3) std::cout << s << ' ';
// deduction guide for array creation (since C++17) [[maybe_unused]] std::array a4{3.0, 1.0, 4.0}; // -> std::array<double, 3>
