c++使用while和switch结构,实现输入月份,输出对应的季节.

可以反复输入月份数，显示对应的季节。
选择结构我会了，但是怎么加入循环结构？
#include
using namespace std;
int main()
{
int month;

cout<<"请输入月份："< cin>>month;

switch(month)
{
case 3:
case 4:
case 5:
cout<<"春季";break;
case 6:
case 7:
case 8:
cout<<"夏季";break;
case 9:
case 10:
case 11:
cout<<"秋季";break;
case 12:
case 1:
case 2:
cout<<"冬季";break;
default:
cout<<"你输入的月份不存在.";break;
}

return 0;
}

//输入0退出循环
#include
using namespace std;
int main()
{
int month;

cout<<"请输入月份："< cin>>month;
while(month)
{
switch(month)
{
case 3:
case 4:
case 5:
cout<<"春季";break;
case 6:
case 7:
case 8:
cout<<"夏季";break;
case 9:
case 10:
case 11:
cout<<"秋季";break;
case 12:
case 1:
case 2:
cout<<"冬季";break;
default:
cout<<"你输入的月份不存在.";break;
}
}
return 0;
}
