Output appears the same also this way:

static void Main(string[] args)
{
int[,] myArray = new int[5, 5];
int row, i;
int n = 1;

for (row = 0; row < 5; row++)
{
for (i = 0; i < 5; i++)
{
myArray[row, i] = n;
if (row == 1 && i == 2) Console.Write(" \t");
else Console.Write("{0} \t", n);

if (n!=26) n++;
if((i+1)%5==0) Console.WriteLine("\n");
}
}
Console.ReadLine();
}

Let pointer p point to the index 1 elem (value=2) of the array.
int *p= a+1;
Let pointer q point to the index 6 elem (value=5) of the array.
int *q= a+6;
-Expression q-p is the subtraction of address of the index 6 element and the address of index 1 elem of the array. So, the result is 5.
-Expression *p+*q is the sum of the value of index 1 elem (2) and the value of index 6 elem (5). So, the result is 7.
In conclusion, the output is 57.

Find the output of following code
main()
{
int a[] = {1,2,9,8,6,3,5,7,8,9};
int *p= a+1; int *q= a+6;
cout<< q-p <<*p+*q; }

Option Explicit
Dim Cn as New ADODB.Connection
Private Sub_Form_Load()
Cn.Open "Provider=SQLOLEDB; Data Source=ServerName; Initial Catalog=DatabaseName;UserID=UserName; Password=Passw"
End Sub
You will need to replace ServerName with the name of your server (installed SQL Server), DatabaseName withe the name of your data file that you want to connect to, UserName with the name of the user to login to SQL Server, and Passw with the password used to login to SQL Server.
