C# Reading and writing to console

Reading from the console => Console.ReadLine
Writing to the console => Console.WriteLine
       Two ways to write a console
            1. Concatenation
            2. Place holder which is most preferred


Example with Concatenation

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Enter First Name");
        string FirstName = Console.ReadLine();
        Console.WriteLine("Enter Last Name");        
        string LastName = Console.ReadLine();
        Console.WriteLine("Hello "+FirstName +LastName);
        Console.ReadLine();
    }

}

Output:
Enter First Name
Balamurugan
Enter Last Name
Ganesan
Hello BalamuruganGanesan



Example with Place holder

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Enter First Name");
        string FirstName = Console.ReadLine();
        Console.WriteLine("Enter Last Name");        
        string LastName = Console.ReadLine();
        Console.WriteLine("Hello {0} {1}", FirstName, LastName);
        Console.ReadLine();
    }

}

Output

Note1:
C# is a case sensitive

Note2:
Difference between Write and WriteLine

Write() method => Output values to the screen without newline character
WriteLine() method => Output will start on a new line
