Hi,

This is homework? You could try :

using System;
namespace ConsoleDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            var str = new string[] { "a", "b\n", "c", "d" };

            for (var i = 0;i<str.Length;i++) // iterate over each array index
            {
                if (!str[i].EndsWith("\n")) // Check if the string enfs with \n
                {
                    str[i] += "\n"; // append extra string if not
                    
                }
                Console.Write(str[i]); // Not WriteLine but shown on a separate line on the console
            }
            Console.WriteLine("End"); // To check \n was appended to the last element
        }
    }
}

if(!stringVariable.Contains("\n"))
{
  
  stringVariable = stringVariable + "\n";

}
