Dev-C++中一个C语言程序的小问题

Question

//根据用户键入的整数求和 
#include<stdio.h>

int main(void)
{
	long num;
	long sum = 0L;
	int status;
	
	printf("Please enter an integer to be summed ");
	printf("(q to quit): ");
	status = scanf("%ld", &num);  
	while(status == 1);
	{
		sum = sum + num;
		printf("Please enter next integer (q to quit): ");
		status = scanf("%ld", &num);
	}
	printf("Those integers sum to %ld.\n", sum);
	
	return 0;
 } 

为什么会是死循环呢？按照书上敲的应该没问题啊？
