不知道为什么老是第10步出错...可是我怎么看也不知道错在哪里啊？？？大侠帮我瞧瞧....错误报告在下面
先谢过了



#include <stdio.h>

int average(int a,int b,int c);

void main(void)
{
    int a=1,b=2,c=3;
    int a2=1234,b2=2345,c2=3456;
    int a3=9876,b3=2345,c3=1;
    int y = average(a,b,c,);
    int y2= average(a2,b2,c2);
    int y3= average(a3,b3,c3);

    printf("\n the average is %d",y);
    printf("\n the average is %d",y2);
    printf("\n the average is %d",y3);

}
int average(int a,int b, int c)
{
    return (a+b+c)/3;
}

错误报告；
10 illegal expression
10 too marny arguments to “average”
10 syntax error;found;expecting"}"

我郁闷啊...............................

谢谢大哥了
