| deque::pop_back |
public member function |
Delete last element
Removes the last element in the deque container, effectively reducing the container size by one.
This calls the removed element's destructor.
Parameters
none
Return value
none
Example
// deque::pop_back
#include <iostream>
#include <deque>
using namespace std;
int main ()
{
deque<int> mydeque;
int sum (0);
mydeque.push_back (10);
mydeque.push_back (20);
mydeque.push_back (30);
while (!mydeque.empty())
{
sum+=mydeque.back();
mydeque.pop_back();
}
cout << "The elements of mydeque summed " << sum << endl;
return 0;
}
|
In this example, the elements are popped out from the end of the
deque after they are added up in the sum. Output:
The elements of mydeque summed 60
|
Complexity
Constant.
