int main()
{
	int low, up, t;
	int sum = 0;

	printf("Enter lowe and upper integer limits:");
	scanf("%d %d", &low, &up);
	t = low;

	while (low < up)
	{
		sum = 0; //在每次循环前重置 sum  
		t = low;
		for (low; low < up + 1; low++)
		{
			sum = sum + low * low;
		
		}
		printf("The sum of tje squares from %d to %d is %d\n", t * t, up * up, sum);
		printf("Enter next set of limits:");
		scanf("%d %d", &low, &up);
		
	}
