The boast string will help you to understand the concept. Actually C# has pretty neater treatment with strings. Start a fresh COnsole Application project and here is what we usually do when we have thing like this

            int count=20;
            float am=100 ;
            string symbol=” $”;
            string boastStr=”minutes”;
            double   min=2.50;
  Console.Write(“Boast string : I have finished ” + count + ” Apples and Oranges ( ” + am + symbol + “) in ” + min + ” ” + boastStr + ” , wow”) ;

The message is just a joke , lol.

 You can put values inside within a single string by using a { }, curly braces and cardinals instead of the old fashioned + operator, but limited to console only. It will look like,
“I have to reach the station at {0}”, min . Can also use many variables in a string.

Lets convert our boast string too

            Console.WriteLine (“\nBoast string : I have finished {0} Apples and Oranges (  {1} {2}  ) in   {3}  {4} , wow”,count,am,symbol,min,boastStr );

Remember it’s only work with Console.Write().
