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:
CPP
CPP
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;
}
// C++ program to demonstrate
// example of end() function.
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:
Example 2:-
valarray contains= 10 20 30 40 50
// 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;
}
// C++ program to demonstrate
// example of end() function.
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
