C Program Linked lists

Description:

typedef struct node_ {

int data;

struct node_* next;

}node;

void print_list(node* list);

Parameters:

list: A pointer to the head of a single linked list

Return: none

See example output, prints out the linked list

void free_list(node* list);

Parameters

list: A pointer to a single linked list

Return: None

This function should free each node in the linked list

node* create_list(char* file);

Parameters:

file: The name of the input file

Return: The head of the linked list

This function will open the input file and will build a linked list by malloc()ing a node for each of the numbers and linking them together.

int main(int argc, char* argv[]);

Main will read in an input file as a command line argument and then create a linked list, print it out and then free it.

Input file:

1050 2050 2270 3050 3280 3330 3380 4050 4320 4520 4850 4970 4980 

Sample output:

1050->2050->2270->3050->3280->3330->3380->4050->4320->4520->4850->4970->4980->NULL
