runtime error in code

[Lenjaku]

Hi, I wrote this code and I don't seem to get why it gives me a runtime error...
Any help in the matter will be much apreciated.

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

typedef struct node
{
	int info;
	struct node * next;
}*listptr;



void print(listptr list)
{
	listptr p;
	p=list;
	while (p)
	{
		printf("%d ",p->info);
		p=p->next;
	}
	
}



void push(struct node **s,int x)
{
	struct node *q;
	q=(struct node *)malloc(sizeof(struct node));
	q->info=x;
	q->next=*s;
	*s=q;
}



void main()
{
	int n;
	listptr list;

	scanf("%d",&n);
	
	while (n!=999)
	{
		push(&list,n);
		scanf("%d",&n);
	}
	print(list);
}

Looks like you never set a next element to NULL, so you have to end of your list. If you initialize list to NULL in main, the first time you call push, it will set q->next to NULL.

Also:

1) Don't cast malloc.

2)void main() should be int main(void) and return 0.

Thankies :3 NULL does the job!!
