std::forward_list::max_size() is an inbuilt function in CPP STL which returns the maximum number of elements can be held by forward_list. This value depends on system or library implementation.
Syntax:
forwardlist_name.max_size ()
Parameters: The function does not accept any parameters.
Return value:The function returns the maximum numbers that can be stored into the forward_list.
Below program demonstrates the above function:
CPP
// C++ program to illustrate the // max_size() function #include <bits/stdc++.h> using namespace std;
int main()
{ // initialising the forward list
forward_list< int > f;
// print max number of values that
// can be held by forward_list
cout << "Max_size of the list is "
<< f.max_size() << endl;
return 0;
} |
Output
Max_size of the list is 1152921504606846975
Time Complexity: O(1)
Auxiliary Space: O(1)
