Sum of 2 Dimensional Array

#include <iostream>
using namespace std;

void main ()
int exam[10][10];
int ave[10];
int x, y;
int sum;

cout<<"Input number of Subjects ";
cout<<"Input of number of exams per subjects ";

for (int i = 1 ; i <= x ; i++)
for (int j = 1 ; j <= y ; j++)

cout<<"Subject "<<i<<endl;
cout<<"Input grades on Exam "<<j<<" ";

for(int i=0; i<x; i++)
{ sum=0;
for(int j=0; j<y; j++)
sum +=exam[x][y];

ave[y] = sum/y;
cout<<"subject "<<i+1<<"average is "<<ave[y];

system ("pause");

This is obviously the wrong code.

The output should be the average of the exam per subject. Which is I don't know how to do it. Help please?
it is exam[i][j] not exam[x][y]

the same for ave[i] not ave[y]

an array starts with 0. hence the loop is supposed to be
for (int i = 0 ; i < x ; i++)
for (int j = 0 ; j < y ; j++)

if you want start with 1 in your cout just put i + 1 etc
