请教一个程序在vc++里面编译不能通过的问题

瞬间思路

为什么我的这段代码在vc++里 编译会有这种错误呢？是什么原因呢？

代码如下
#include "stdio.h"
void cour_ave (int a, int b,float score[])
{
        int course ,stud;
        float total1,aver1;
        for (course = 0; course < b; course++)
        {
                total1 = 0 ;
                for ( stud = 0;stud < a;stud++)
                        total1 = total1 + score[stud*b+course];
                aver1 = total1 / a;
                printf ("average of course %d is :%6.2f\n",course,aver1);
        }
        return;
}


void stud_ave (int a, int b,float score[])
{
        int course ,stud;
        float total2,aver2;
        printf("\n";
        for (stud = 0;stud < a ;stud++)
        {
                total2 = 0;
                for (course = 0;course < b;course ++)
                        total2 = total2 + score[stud * b + course ];
                aver2 = total2 / b;
                printf ("average of student %d is %6.2f\n",stud,aver2);
        }
        return;
}


#define a 4
#define b 3
void main ()
{
        void cour_ave (int x,int y,float score[]);
        void stud_ave(int x,int y,float score[]);
        float score[a]={{89,78,56},{88,99,100},{72,80,61},{60,70,75}};
        cour_ave(a,b,score);
        stud_ave(a,b,score);
        return;
}


编译提示信息如下：

ompiling...

请帮我想想

whyglinux

cour_ave(a,b,score[0]);
stud_ave(a,b,score[0]);

或者

cour_ave(a,b,&score[0][0]);
stud_ave(a,b,&score[0][0]);
