输入字母就刷屏！怎么回事呢？
今天编一个很简单的程序试了一下其他都好就是一输入字母就刷屏，不知道是什么原因，恳请各位大虾帮忙啊！
下面是程序：
#include <iostream>

void time(int hours,int minutes);

int main()
{
using namespace std;

int hours,minutes;

cout < < "Enter the number of hours: ";

cin> > hours;

while (hours <0 || hours> 12)
{
cout < < "Your hours is wrong! Please input it again! ";

cin> > hours;
}

cout < <endl;

cout < < "Enter the number of minutes: ";

cin> > minutes;

while (minutes <0 || minutes> 60)
{
cout < < "Your minutes is wrong! Please input it again! ";

cin> > minutes;
}

cout < <endl;

time(hours,minutes);

cin.get();

cin.get();

return 0;

}

void time(int hours,int minutes)
{
using namespace std;

cout < < "Time: " < <hours < < ": ";

if(minutes <10)
{
cout < < "0 " < <minutes < <endl;
}
else
cout < <minutes < <endl;
}

[解决办法]
在while循环中cin> > 的下面加入cin.clear(),cin.sync()两行代码，用以清除输入流缓冲区
