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;
} |
Output:
valarray contains= -10 -20 -30 -40
