Creating Main Class

First of all, we have to create our Main class.

 public static void Main()
{
    string str = "a!!!b.c.d,e'f,ghi"; //Initialize string that we will reverse
    Console.WriteLine("Input string: " + str);
    string str2 = Reverse(str); //Reversing string
    Console.WriteLine("Output string: " + str2);
}
