title: Password check without using RegEx and/or lists/rules
body: <p>I've searched the forums and all over google and have yet to find an answer to my question. I'd like to create a simple program with one single for loop with if/if else statements. Is this possible without using RegEx or lists/rules? </p>
  
  <p>I'd like it to fit these requirements:</p>
  
  <p>Length 8.
  At least one digit.
  At least one upper case.
  At least one lower case.</p>
  
  <p>This is what I've come up with thus far and I don't understand why it doesn't work? The reason I have the if statements without else if's is because I want all error messages to printed if the conditions are not met. Apologies for dumb questions, I'm new to c#.</p>
  
  <pre><code>static void Main(string[] args)
  {
      var password = Console.ReadLine();
  
      for (var i = 0; i &lt; password.Length; ++i)
      {
          bool hasDigit = char.IsDigit(password[i]);
          bool hasUpperCase = char.IsUpper(password[i]);
          bool hasLowerCase = char.IsLower(password[i]);
  
          if(password.Length &lt; 8)
          {
              Console.WriteLine("Password length should be 8 symbols or more.");
          }
          if(!hasUpperCase)
          {
              Console.WriteLine("Password should contain at least one uppercase letter.");
          }
          if(!hasLowerCase)
          {
              Console.WriteLine("Password should contain at least one lowercase letter.");
          }
          if(!hasDigit)
          {
              Console.WriteLine("Password should contain at least one digit.");
          }
  
          password = Console.ReadLine();
      }
  
      Console.WriteLine("Your password is properly set!");
      Console.ReadLine();
  }
