刚学了几天C, 我用dev c++,
安装例子写了练习题，不知道为什么不编译。。。请指教， code 如下：
#include <stdio.h>
#include <stdlib.h>
int main()
{
    float length, width;
    int fnum;
    printf("Please enter the floor number:\n");
    scanf("%d",&fnum);   
    printf("Please enter the length of the area/room:\n");
    scanf("%f", &length);
    printf("Please enter the width of the area/room:\n");
    scanf("%f", &width);   
    area(length, width, fnum);   
}
area(size, wide, num)
float size, wide;
int num;
{
    float area;
    area=size*wide;
    printf("The area of the bluiding %.2f and %d floors", area, num);
    return 0;
}

#include <stdio.h>
#include <stdlib.h>

 int area(float size, float wide,int num)

{
    float area;
    area=size*wide;
    printf("The area of the bluiding %.2f and %d floors", area, num);
    return 0;
}

int main()
{
    float length, width;
    int fnum;
    printf("Please enter the floor number:\n");
    scanf("%d",&fnum);
    printf("Please enter the length of the area/room:\n");
    scanf("%f", &length);
    printf("Please enter the width of the area/room:\n");
    scanf("%f", &width);
    area(length, width, fnum);
}

谢谢，编译了， 虽然对这个传递参数还有点迷糊。。。

跟我想的一样吖o(∩_∩)o...
