Queue function

Suppose s structure function is defined as:

Code:

typedef struct node {
                 char *name;
                 char phone[9];
                 struct node *next;
                 } queue;

I need to write a function void insert_queue( queue **q_front, queue **q_rear, char *str, char str_num[]), such that *q_front point to the 1st node, *q_rear point to the last node. It adds new node with name str and phone str_num at the end queue while updating q_rear and q_front.

I came out with the below definition but the program don't work. Hope anyone can spot my error. Thanks

Code:

void insert_queue( queue **q_front, queue **q_rear, char *str, char str_num[]){
* q_front= (queue*) malloc(sizeof (struct node));
* q_front-> name= *str;
* q_front-> phone= str_num;
* q_front-> next= NULL;

if (*q_rear !=NULL)
*q_rear->next=*q_front;
*q_rear= *q_front;
return *q_rear;
}

Code:

* q_front= (queue*) malloc(sizeof (struct node));

Don't cast malloc - it may hide problems, and nothing good ever comes from it.

Code:

*q_rear= *q_front;

Are you supposed to ALWAYS set this?
