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 ";
cin>>x;
cout<<"Input of number of exams per subjects ";
cin>>y;
for (int i = 1 ; i <= x ; i++)
for (int j = 1 ; j <= y ; j++)
{
cout<<"Subject "<<i<<endl;
cout<<"Input grades on Exam "<<j<<" ";
cin>>exam[x][y];
}
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];
cout<<endl;
}
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
the same for
an array starts with 0. hence the loop is supposed to be
[EDIT]
if you want start with 1 in your cout just put
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

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