list::max_size

public member function
size_type max_size () const;

Return maximum size

Returns the maximum number of elements that the list container can hold.

This is the maximum potential size the container can reach due to system or library implementation limitations.

Parameters

none

Return Value

The maximum number of elements a list container can have as its content.

Member type size_type is an unsigned integral type.

// list::max_size
#include <iostream>
#include <list>
using namespace std;
int main ()
{
  unsigned int i;
  list<int> mylist;
  cout << "Enter number of elements: ";
  cin >> i;
  if (i<mylist.max_size()) mylist.resize(i);
  else cout << "That size exceeds the limit.\n";
  return 0;
}


Here, member max_size is used to check beforehand whether the requested size will be allowed by member resize.

Complexity

Constant (recommended). Linear in some implementations.
