stack::push


public member function
void push ( const T& x );

Add element

Adds a new element at the top of the stack, above its current top 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 stack).


Return value

none

// stack::push/pop
#include <iostream>
#include <stack>
using namespace std;

int main ()
{
  stack<int> mystack;

  for (int i=0; i<5; ++i) mystack.push(i);

  cout << "Popping out elements...";
  while (!mystack.empty())
  {
     cout << " " << mystack.top();
     mystack.pop();
  }
  cout << endl;

  return 0;
}


Output:
Popping out elements... 4 3 2 1 0



Complexity

Constant.
