TC2.0中
一个已知高度通过输入长和宽来计算长方体体积的代码  
为什么ctrl+F9（运行）之后输入了长和宽之后页面消失  在第二次运行后才会输出结果呢？
#include<stdio.h>                                    
#define Height 10

int calculate(int Long,int Width);

int main()
{
     int m_Long;
     int m_Width;
     int result;

     printf("The height of the rectangle is: %d\n",Height);

     printf("Please enter the length of the rectangle\n");
     scanf("%d",&m_Long);

     printf("Please enter the width of the rectangle\n");
     scanf("%d",&m_Width);

     result=calculate(m_Long,m_Width);
     printf("The volumeof the rectangle is:");
     printf("%d\n",result);
     return 0;
}

int calculate(int Long,int Width)
{
     int result=Long*Width*Height;
     return result;
}

在最后加system（“pause”）；
我明白了
