C++ Question

Question

So I have this code that I expected to output a bunch of zeros, but instead output a huge random number. I'm still getting my grip on the language here, so could anyone explain what's happening here? Here's the code:
#include <iostream>
using namespace std;

int main()
{
const int M=20;
const int N=10;
int field[M][N]={0};
for(int i=0; i<10;i++)
cout<<field[M][N]<<endl;
return 0;
}

Answer 1

Nevermind I see what's happening. I'm calling dimension [20][10] when that was not initialized. The arrays dimensions only go up to [19][9].
