Solution
using System;
public class Password
{
public static void Main()
{
int user, pass;
int counter = 0;
do
{
Console.Write("Enter a user: ");
user = Convert.ToInt32(Console.ReadLine());
Console.Write("Enter a password: ");
pass = Convert.ToInt32(Console.ReadLine());
if ((user != 12) || (pass != 1234))
{
Console.WriteLine("Login Error");
counter++;
}
}
while ( ((user != 12) || (pass != 1234)) && (counter != 3));
if ((user != 12) || (pass != 1234))
Console.WriteLine("Logged out!");
else
Console.WriteLine("Login successful");
