        // There is not an exact equivalent of vb.net strReverse in C# so we simulate it
        // Example #1: 	StrReverse(string) - returns a string with the characters of the 
        // string in reverse order
        //****************************************************************************************

        string strString1 = "Hello World";
 
 
        // Return Uppercase
        Console.WriteLine(SimulateStrReverse.StrReverse(strString1)); //Returns dlroW olleH
 
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
 
 
        //Prevent console from closing before you press enter
