C++ STL program to get the elements of an array using array:get function template
#include <array>
#include <iostream>
using namespace std;
int main()
{
array<int,5> arr {10, 20, 30, 40, 50};
cout<<"element at index 0: "<<get<0>(arr)<<endl;
cout<<"element at index 1: "<<get<1>(arr)<<endl;
cout<<"element at index 2: "<<get<2>(arr)<<endl;
cout<<"element at index 3: "<<get<3>(arr)<<endl;
cout<<"element at index 4: "<<get<4>(arr)<<endl;
return 0;
}
Output
element at index 0: 10
element at index 1: 20
element at index 2: 30
element at index 3: 40
element at index 4: 50
