C++ Set Library - end Function

Description

It returns an iterator referring to the past-the-end element in the set container.

Declaration

Following are the ways in which std::set::end works in various C++ versions.

C++98

iterator end();
const_iterator end() const;

C++11

 iterator end() noexcept;
const_iterator end() const noexcept;

Return value

It returns an iterator referring to the past-the-end element in the set container.

Time complexity

Example

The following example shows the usage of std::set::end.

#include <iostream>
#include <set>

int main () {
   int myints[] = {50,40,30,20,10};
   std::set<int> myset (myints,myints+10);

   std::cout << "myset contains:";
   for (std::set<int>::iterator it = myset.begin(); it!=myset.end(); ++it)
      std::cout << ' ' << *it;

   std::cout << '\n';

   return 0;
}

The above program will compile and execute properly.

myset contains: -107717047 0 1 10 20 30 40 50 29015
