C/C++ :: Linked List Inputs From The User?

#include <iostream>
using namespace std;
void insert(int data, int positionOf_n);
void print();
struct node {
int data;
struct node *next;

[code]....

this is the original code which use the insert function call in the main as predefined that doesn't allow the user to input the value that they want

#include <iostream>
using namespace std;
void insert(int data, int positionOf_n);
void print();
struct node {
int data;

[code]....

and this the code which i tried to replace the limitation of the above code by using two for loops in the main function instead of the <insert(5,2)> from the above code which allow the user to insert it own values to the linked list, but it keeps crashing.
