Array data() in C++ STL with Examples
The array is a collection of elements of the same data type stored in continuous memory locations.
C++ standard library contains many libraries that support the functioning of arrays. One of them is an array data() method.
The array data() in c++ returns a pointer pointing to the first element of the object.
Syntax
array_name.data();
Parameter
There are no parameters accepted by the function.
Return type
A pointer to the first element of the array.
Example

Live Demo
#include <bits/stdc++.h>
using namespace std;
int main(){
array<float, 4> percentage = { 45.2, 89.6, 99.1, 76.1 };
cout << "The array elements are: ";
for (auto it = percentage.begin(); it != percentage.end(); it++)
cout << *it << " ";
auto it = percentage.data();
cout << "\nThe first element is:" << *it;
return 0;
}Output
The array elements are: 45.2 89.6 99.1 76.1
The first element is:45.2
