99 bottles of beer csharp example

99 bottles of beer lyrics for reference just in case you don't know how the song goes

Simple count down with while loop

99Bottles_whileSimple.cs

The simple version uses three variables <csharp> string strBottles = "bottles"; string strLineOne = ""; int intBottles = 99; </csharp>

The string strBottles is used to change the word 'bottles' to bottle when the bottle count gets to 1.

2 bottles of beer on the wall.  is correct but
1 bottles of beer on the wall is not so we will use a variable and an if stement to change the
word bottles to bottle if the intBottles variable = 1

<csharp> //Check for 1 bottle of beer if (intBottles==1) {

  strBottles = " bottle"; //fix 1 bottle of beer

} </csharp>

Now we can create the first line of the verse and write it to the console <csharp> strLineOne = intBottles + " " + strBottles + " of beer on the wall, " + intBottles + " bottles of beer.";

Console.WriteLine (strLineOne); </csharp>

Now we just need to wrap this is a loop and make it count down. the loop may look like <csharp> while (intBottles > 0)

       {
           //Check for 1 bottle of beer
           if (intBottles==1) 
           {
               strBottles = " bottle"; //fix 1 bottle of beer
           }

           strLineOne = intBottles + " " + strBottles + " of beer on the wall, " + intBottles + " bottles of beer.";

           Console.WriteLine (strLineOne);
           
           intBottles--;
       }

</csharp>

the one we made in class <csharp> using System; using System.Collections.Generic; using System.Text;

namespace _9BottlesWhile {

   class Program
   {
       static void Main(string[] args)
       {

           int intBottles = 99;
           string strLineOne = "";
           string strLineTwo = "";

           string strBottles = "bottles";

           while (intBottles >= 0)
           {
               if (intBottles == 0)
               {
                   strLineOne = "No more bottles of beer on the wall. No more bottles of beer.";
                   strLineTwo = "Got to the store and buy some more.";

                   Console.WriteLine(strLineOne);
                   Console.WriteLine(strLineTwo);

                   Console.ReadKey();
                   
                   intBottles = 99;  //this line will make it loop forever.
               }
               //Change bottles to bottle when on 1 bottle is left
               if (intBottles == 1)
               {
                   strBottles = "bottle";
               }
               
               strLineOne = intBottles + " " + strBottles + " of beer on the wall, ";
               strLineOne += intBottles + " " + strBottles + " of beer.";

               intBottles--;

               //Change bottles to bottle when on 1 bottle is left
               if (intBottles == 1)
               {
                   strBottles = "bottle";
               }
               if (intBottles == 0)
               {
                   strBottles = "bottles";
               }

               strLineTwo = "Take one down and pass it around. " + (intBottles); 
               strLineTwo += " " + strBottles + " of beer on the wall";

               Console.WriteLine(strLineOne);
               Console.WriteLine(strLineTwo);
               
           }

           Console.ReadKey();

       }
   }

} </csharp>
