我编写了以下的代码，[u][color=800000]可是到了运行窗口后，我输入了值，一按回车运行窗口就关了[/color][/u]，我想知道为什么，怎么样可以让它不关闭，显示结果！这个代码是没有问题，我就是想知道我的电脑里是不是少了什么东西，不能显示结果。像8楼那样显示出It is the 114th day，拜托了[code=c]我用DEV-C++ 4.9.9.2编写
main()
{
      int day,month,year,sum,leap;
      printf("\nplease input year,mouth,day\n");
      scanf("%d,%d,%d",&year,&month,&day);
      switch(month)
      {
                    case 1:sum=0;break;
                    case 2:sum=31;break;
                    case 3:sum=59;break;
                    case 4:sum=90;break;
                    case 5:sum=120;break;
                    case 6:sum=151;break;
                    case 7:sum=181;break;
                    case 8:sum=212;break;
                    case 9:sum=243;break;
                    case 10:sum=273;break;
                    case 11:sum=304;break;
                    case 12:sum=334;break;
                    default:printf("data error");break;
                    }
                    sum=sum+day;
                    if(year%400==0||(year%4==0&&year%100!=0))
                       leap=1;
                    else
                       leap=0;
                    if(leap==1&&month>2)
                    sum++;
                    printf("It is the %dth day.",sum);
                    getchar();
                    return 0;
                    }
