大家帮忙看下 这个程序那里出问题了？
//777
#include <iostream>

using namespace std;

viod show1(double [][b]);
double pj(double [][b]);
double max(double [][b]);
main()
{
const int a=2;
const int b=3;
double A[a][b]={12.1,14.2,15.2,11.4,15.2,14.9};
cout<<"数组A是:"<<endl;
show1(A);
cout<<"数组A的平均值是:"<<pj(A)<<endl;
cout<<"数组A的最大值是:"<<max(A)<<endl;
return 0;
}
//函数show()的定义
viod show1(double q[][b])
{
for(int i=0;i<a;i++)
{
for(int y=0;y<b;y++)
cout<<setw(5)<<q[i][y]<<endl;
}
return 0;
}
//函数pj()的定义
double pj(double n[][b])
{
double sum=0;
double pj1;
for(int i=0;i<a;i++)
{
for(int y=0;y<b;y++)

}pj1=sum/double(6);
return pj1;
}
//函数max()的定义
double max(double m[][b])
{double max1=m[0][0];
for(int i=0;i<a;i++)
for(int y=0;y<b;y++)
{
if(max1<m[i][y])
max1=m[i][y];
}
return max1;
}
