How to get the first element of an array in C++

In this tutorial, we are going to learn about how to get the first element of an array in C++.

Consider, we have the following array.

array<int,4> nums {20, 30, 40, 50};

Now, we want to get the first element 20 from the above array.

To get the first element (20) from the array, we can use the subscript operator [ ] by passing an index 0.

In C++ arrays are zero-indexed, so the first element index of an array is 0.

Here is an example:

#include <iostream>
#include <array>
using namespace std;

int main()
{
    array<int,4> nums {20, 30, 40, 50};
    int firstElement = nums[0];

    cout<<"First element is: "<<firstElement<<endl;

    return 0;
}

Output:

20
