| list::pop_back |
public member function |
Delete last element
Removes the last element in the list container, effectively reducing the list size by one.
This calls the removed element's destructor.
Parameters
none
Return value
none
Example
// list::pop_back
#include <iostream>
#include <list>
using namespace std;
int main ()
{
list<int> mylist;
int sum (0);
mylist.push_back (100);
mylist.push_back (200);
mylist.push_back (300);
while (!mylist.empty())
{
sum+=mylist.back();
mylist.pop_back();
}
cout << "The elements of mylist summed " << sum << endl;
return 0;
}
|
In this example, the elements are popped out from the end of the list after they are added up in the sum. Output:
The elements of mylist summed 600

Complexity
Constant.
