程序代码：

#include <stdio.h>
#define Height 10  

int calculate(int Long,int Width);

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

        printf("长方形的高为：\n",Height);

        printf("请输入长方形的长为：\n");
        scanf("%d",&m_Long);

        printf("请输入长方形的宽为：\n");
        scanf("%d",&m_Width);

        result=calculate(m_Long,m_Width);
        printf("长方形体积是：");
        printf("%d\n",result);
        return 0;
}


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