2d Array Reverse Crash

[neel3123]

Write your question here.
Hello my program takes an input turns it into a 2d array then reverses it. When I try to output my array it outputs 3 negative numbers then crashes.
Error:
A buffer overrun has occurred in 2d Array Reverse.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program.

// 2d Array Reverse.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
	int board[2][3];
	int width=3;
	int height=4;
	cout<< "Enter your First Row First Number"<<endl;
	cin>> board[0][1];
	cout<< "Enter your First Row Second Number"<<endl;
	cin>> board[0][2];
	cout<< "Enter your First Row Third Number"<<endl;
	cin>> board[0][3];
	cout<< "Enter your Second Row First Number"<<endl;
	cin>> board[1][1];
	cout<< "Enter your Second Row Second Number"<<endl;

	cin>> board[3][1];
	cout<< "Enter your Fourth Row 3rd Number"<<endl;
	cin>> board[3][2];
	cout<< "Enter your Fourth Row 4th Number"<<endl;
	cin>> board[3][3];
	for(int i = 0; i<width; i++)
	{
		for(int j=0; j<height; j++)
		{
			cout<< board[i][j] << " "<<endl;
		}
	}
	return 0;
}

You have your array dimensions mixed up. You initialize an array to by 3x4, but you try to enter numbers into a 4x3 array. The for loop is correct for a 3x4 array.

So how do I do it correctly?

[Yay295]

The left [] should only go up to 2, and the right [] should go up to 3.

it still gives me

(I updated the code)

Sorry, I'm not getting any errors. Even if I enter bad data the program still completes.

int board[2][3];

board is defined to only have two rows and three columns.

[0,0][0,1][0,2]
[1,0][1,1][1,2]

The code is trying to access elements that don't exist.

[neel3123]

I changed it to [3][4] and same problem.

[wildblue]

OK, 3 rows by 4 columns is this.

[0,0][0,1][0,2][0,3]
[1,0][1,1][1,2][1,3]
[2,0][2,1][2,2][2,3]


This code still tries to access elements that don't exist.

cout<< "Enter your Fourth Row 1st Number"<<endl;
cin>> board[3][1];
cout<< "Enter your Fourth Row 3rd Number"<<endl;
cin>> board[3][2];
cout<< "Enter your Fourth Row 4th Number"<<endl;
cin>> board[3][3];

The first row, first number is [0,0]

cout<< "Enter your First Row First Number"<<endl;
cin>> board[0][1];

Oh, Thanks.
