vector_pro::not_empty

C++

bool not_empty() const noexcept;

Test whether the container is empty

Returns whether the vector is not empty (i.e. whether its size more than 0).

Parameters

none

Return value

false if the container size is 0, true otherwise.

Example

C++

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

/**
 * Output:
 * total: 55
 */

int main ()
{
  vector_pro<int> myvector;
  int sum (0);

  for (int i=1;i<=10;i++) myvector.push_back(i);

  while (myvector.not_empty())
  {
     sum += myvector.back();
     myvector.pop_back();
  }

  std::cout << "total: " << sum << '\n';

  return 0;
}

Complexity

Constant.
