Thread: Program executes, but doesn't start

I'm working on a project right now that involves linked lists. I've got part of it done, and it complies without any errors currently. However, when I execute it, nothing happens. It apparently doesn't even start int main.

Here's the program:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

struct listNode
{
        char fname[40];
        char lname[40];
        char address[100];
        char pcode[6];
        char phone[10];
        struct listNode *nextPtr;
};

typedef struct listNode ListNode;
typedef ListNode *ListNodePtr;

void insert (ListNodePtr *sPtr);
void printList (ListNodePtr currentPtr);


int main ()
{
        ListNodePtr startPtr = NULL;

        insert(&startPtr);
        printList(startPtr);
}

void insert (ListNodePtr *sPtr)
{
        ListNodePtr newPtr;
        ListNodePtr previousPtr;
        ListNodePtr currentPtr;

        newPtr = malloc(sizeof(ListNode));

        char fname[40];
        char lname[40];
        char address[100];
        char pcode[6];
        char phone[10];
        char c;

        int cnt = 0;

        printf("First Name: ");
        while (c != '\n');
        {
                scanf("%c", &fname[cnt]);
                cnt++;
        }
        cnt = 0;

        printf("Last Name: ");
        while (c != '\n');
        {
                scanf("%c", &lname[cnt]);
                cnt++;
        }
        printf("Address: ");
        while (c != '\n');
        {
                scanf("%c", &address[cnt]);
                cnt++;
        }
        cnt = 0;

        printf("Postal Code: ");
        while (c != '\n');
        {
                scanf("%c", &pcode[cnt]);
                cnt++;
        }
        printf("Phone Number: ");
        while (c != '\n');
        {
                scanf("%c", &phone[cnt]);
                cnt++;
        }
        cnt = 0;

        strcpy(fname, newPtr -> fname);
        strcpy(lname, newPtr -> lname);
        strcpy(address, newPtr -> address);
        strcpy(pcode, newPtr -> pcode);
        strcpy(phone, newPtr -> phone);

        newPtr -> nextPtr = NULL;

        previousPtr = NULL;
        currentPtr = *sPtr;

        previousPtr -> nextPtr = newPtr;
        newPtr -> nextPtr = currentPtr;
}
void printList (ListNodePtr currentPtr)
{
        if (currentPtr == NULL)
        {
                printf("List is empty.\n\n");
        }
        else
        {
                printf("The list is:\n");
                while (currentPtr != NULL)
                {
                        printf("%s\n", currentPtr -> fname);
                        printf("%s\n", currentPtr -> lname);
                        printf("%s\n", currentPtr -> address);
                        printf("%s\n", currentPtr -> pcode);
                        printf("%s\n", currentPtr -> phone);

                        currentPtr = currentPtr -> nextPtr;
                }
                printf("NULL\n\n");
        }
}

However, when I execute it, nothing happens. I've put random printf statements in to see where it stops, and even ones I put at the beginning of main didn't execute. What am I missing here?
