哪位大哥帮我看看这个程序错在什么地方啊?
#include<iostream.h>
void main(){
int i,j,k;
int fun(int c[],int d[]);
int a[][3]={(300,200,280),(250,240,210),(150,200,180)};
int b[]={3500,3800,3800}
j=fun(a[][3],b[]);
cout<<"the sum is"<<j<<endl;
fun(int c[][3],int d[]){
int sum=0;
int m,h,f,n,x;
for(m=0;m<=2;m++)
for(x=0;x<=2;x++)
f=c[m][x];
for(h=0;h<=2;h++)
n=d[h];
sum=f*n;
return sum;
}
