  I understand that but if I input
  
  If user clicks Y how does the program repeat itself....
  
  

• Clark Anderson

  That code should work.

  Well this gives the output to the screen but it makes no decision...just repeats Quit(Y,N)....i need to include an if statement

  Hi,
  
  
  
  Try this,
  
  
     do {
        Console.Write("Quit (Y/N) ");
     } while (Console.ReadLine().ToUpper() != "Y");
  
  
  
  
  cheers,

  You are putting the do in the wrong place if you want to repeat the entire program. You need more like:
  
  using System;

  class Strings

  {

  static void Main()

  {

  do {
  
  string a,b,c;

  a = "Demetrius";

  b = "Salena";

  c = "Family";

  //etc, etc
  
  Console.Write("Quit (Y/N) ");

  } while (Console.ReadLine().ToUpper() != "Y");

  Hi,
  
  
  
  Ok, lets dissect the statement:
  
  
     do {
        // Your logic should be here...
        Console.Write("Quit (Y/N) ");
     } while (Console.ReadLine().ToUpper() != "Y");
  
  
  the statements between do and while clauses would repeat until the expression in the while statement is true.
  
  1. It will enter the loop, execute your logic and display "Quit (Y/N) "
  2. It evaluates the while statement.
  3. Since the while statement includes a call to Console.Readline() the system then waits for an input from the user.
  4. After a key has been entered it is then converted to Upper Case (String.ToUpper() function)..
  5. It would then compare if the letter entered is equal to 'Y'.
     - if yes, then the while statement is me, and the loop terminates.
     - if No, the loops executes in the beginning...

  I understand the concept of the statement...But what makes the program repeat You said the logic goes after the do...but what logic..is there some keyword that i am missing here is the entire sample code:
  
  

  using System;

  class Strings

  {

  static void Main()

  {

  string a,b,c;

  a = "Demetrius";

  b = "Salena";

  c = "Family";

  Console.WriteLine("Enter Your Name");

  Console.Read();

  if ( a == "Demetrius")

  Console.WriteLine("This is Demetrius his girl is {0}", b);

  else if( a != "Demetrius")

  Console.WriteLine("Enter another Choice");

  if ( b == "Salena")

  Console.WriteLine("Salena boyfriend is {0}", a);

  if ( c == "Family")

  Console.WriteLine("{0}, and {1} will start a {2}", a, b, c);

  Console.WriteLine("Press Enter to continue");

  Console.ReadLine();

  do

  {

  Console.Write("Quit (Y/N) ");

  } while (Console.ReadLine().ToUpper() != "Y");

  }

  }

  Hi,
  
  
  
  Yep, you got it right... .
  Your input logic must be placed in the do statement so that it would be included in the loop...

  You know what i think i got it...for the do logic i belive i put the
  

  Console.WriteLine("Enter Your Name");

  Console.Read();
  
  in the do logic so that when i enter N it goes back to these statements...what do you think

  Hi,
  
  
  The decision is in the while statement. If the user does not press a 'Y' key then the loop never ends. Just place the logic inside the while loop...
