Proposed exercise
Write a program to ask the user for his/her login and his/her password (both must be integer numbers) and repeat it as many times as necessary, until the entered login is "12" and the password is "1234".
Output
Solution
using System;
public class Password
{
public static void Main()
{
int user, pass;
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");
}
while ( (user != 12) || (pass != 1234));
Console.WriteLine("Login successful");
}
}
