The end() function is defined in valarray header file. This function returns an iterator pointing to the past-the-end element in the valarray v. Syntax:
template< class T > 
    end( valarray<T>& v );
Parameter: This function takes a mandatory parameter v which represents the valarray object. Returns: This function returns the iterator to the past-the-end in the valarray. Below programs illustrate the above function: Example 1:-
// C++ program to demonstrate
// example of end() function.
  
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    // Initializing valarray
    valarray<int> varr = { 10, 20, 30, 40, 50 };
  
    cout << "valarray contains=";
  
    for (auto i = begin(varr); i != end(varr); i++) {
        cout << ' ' << *i;
    }
  
    cout << endl;
  
    return 0;
}

                    
Output:
valarray contains= 10 20 30 40 50
Example 2:-
// C++ program to demonstrate
// example of end() function.
  
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    // Initializing valarray
    valarray<int> varr = { -10, -20, -30, -40 };
  
    cout << "valarray contains=";
  
    for (auto i = begin(varr); i != end(varr); i++) {
        cout << ' ' << *i;
    }
  
    cout << endl;
  
    return 0;
}
