queue::push |
public member function |
void push ( const T& x ); |
|
Insert element
Adds a new element at the end of the queue, after its current last element. The content of this new element is initialized to a copy of x.
This member function effectively calls the member function push_back of the underlying container object.
Parameters
- x
- Value to be copied to the new element.
T is the first template parameter (the type of the elements stored in the queue).
Return value
none
Example
// queue::push/pop
#include <iostream>
#include <queue>
using namespace std;
int main ()
{
queue<int> myqueue;
int myint;
cout << "Please enter some integers (enter 0 to end):\n";
do {
cin >> myint;
myqueue.push (myint);
} while (myint);
cout << "myqueue contains: ";
while (!myqueue.empty())
{
cout << " " << myqueue.front();
myqueue.pop();
}
return 0;
}

The example uses
push to add a new elements to the queue, which are then popped out in the same order.
Complexity
Constant.
