VS2013执行代码后出现的异常提示

VS2013执行代码后出现的错误提示
用VS2013执行下列代码会出现如图所示的错误提示:
# include <stdio.h>

int main(void)
{
        double number1 = 0.0;
        double number2 = 0.0;
        char operation = 0;

        printf("\n请输入:");
        scanf_s("%lf  %c  %lf", &number1,  &operation,  &number2);

        switch (operation)
        {
        case '+':
                printf("= %lf\n", number1 + number2);
                break;

        case '-':
                printf("=%lf\n", number1 - number2);
                break;

        case'*':
                printf("= %lf\n", number1*number2);
                break;

        case '/':
                if (number2 == 0)
                        printf("输入不合法");
                else
                        printf("= %lf\n", number1 / number2);
                break;

        case '%':
                if ((long)number2 == 0)
                        printf("输入不合法");
                else
                        printf("=%lf", (long)(number1) / (long)(number2));
                break;

        default:
                printf("请输入");
                break;
        }


//        getchar();
        return 0;
}

下图附上VC6.0和VS2013的执行结果

------解决方案--------------------
输入的每个字符之间加一个空格
------解决方案--------------------
崩溃的时候在弹出的对话框按相应按钮进入调试，按Alt+7键查看Call Stack里面从上到下列出的对应从里层到外层的函数调用历史。双击某一行可将光标定位到此次调用的源代码或汇编指令处。
