            int index = 0, count = 1;
            string input = "Welcome to DeveloperPublish website";
            while (index <= input.Length - 1)
            {
                if (input[index] == ' ' || input[index] == '\n' || input[index] == '\t')
                {
                    count++;
                }
                index++;
            }
