vector_pro::pop

C++

value_type pop();

Pop and return the last element

Return a copy of the last element ( Not a reference ) in the vector after destroying, effectively reducing the container size by one.

See also vector_pro::pop_back()

Please note that calling this function on an empty container will get an exception.

It is not highly recommended to use this function; it has been implemented to be useful only in certain situations.

Parameters

none

Return value

A copy of the last element ( Not a reference ).

Example

C++

// vector_pro::pop
#include <iostream>
#include "vector_pro.h"

/**
 * Output:
 * 300
 * 200
 * 100
 */

int main ()
{
  vector_pro<int> myvector;

  myvector.push_back (100);
  myvector.push_back (200);
  myvector.push_back (300);

  std::cout << myvector.pop() << '\n';
  std::cout << myvector.pop() << '\n';
  std::cout << myvector.pop() << '\n';

  return 0;
}

Complexity

Constant.
