Problem

[mjlohr]

What does this program display? I know it has errors in it but I have no idea how to fix them. By the way, I am very new to this. :)

Any ideas?

#include "stdafx.h"
#include<iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[]);
int setw;
{
int arr_3d[4][3] = {{1},
{1, 2},
{1, 2, 3},
{1, 2, 3, }};
int row, col;
for (row = 0; row < 4; ++row)
{
cout << endl;
for (col = 0; row < 3; ++col)
cout << setw(3) << arr_3d[row][col];
}
return 0;
}



Here are the errors:

You're declaring a 4x3 array and attempting to initialise it with something that's not a 4x3 array.

That's a bit confusing to me. Is there any possible way you could explain that a little better?

Thanks :)
