forward_list max_size() in C++ STL with Examples
The forward_list::max_size() is a built-in function in C++ STL which returns the maximum number of elements a forward_list container can hold
Syntax:
forward_list_name.max_size()
Parameters: The function does not accept any parameters.
Return Value: The function returns the maximum number of elements the container can hold.
Below programs illustrate the above function:
Program 1:
// CPP program to demonstrate the// forward_list::max_size() function// when the list is not-empty#include <bits/stdc++.h>using namespace std;int main(){ // declaration of forward list forward_list<int> fl; // assign value fl.assign(5, 8); // prints the elements cout << "The forward_list elements: "; for (auto it = fl.begin(); it != fl.end(); it++) cout << *it << " "; cout << "\nThe max size: " << fl.max_size(); return 0;} |
Output:
The forward_list elements: 8 8 8 8 8 The max size: 1152921504606846975
Program 1:
