Our First Program
In this lesson we are going to try and familiarize ourselves with programming... We are going to initiate a couple of commands and finish the program pretty quickly. The first time that i saw this program it absolutely confused me beyond belief. In the Videos that I have included here I am going to seek to explain each and every line of code and break it down so that it hopefully makes sense.
Please keep in mind that the symbols // make anything typed in after it on that line a comment in the program. Comments in programs are notes for the programmers to read that help people understand what is happening in the program. These lines are ignored by the computer.

The code
using System; // this is the dictionary of keywords that we are going to reference in our program
namespace ConsoleApp1 // this is the name of our program
{
class Program // this is the class that the program is put into
{
static void Main(string[] args) // this is the name of the function that our code fits into
{
Console.WriteLine("Hello World!"); // this is the line of text that will get out putted to the screen for the user to see
}
}
}
namespace ConsoleApp1 // this is the name of our program
{
class Program // this is the class that the program is put into
{
static void Main(string[] args) // this is the name of the function that our code fits into
{
Console.WriteLine("Hello World!"); // this is the line of text that will get out putted to the screen for the user to see
}
}
}

The Assignment
Write 2 of the things below into your program to make it different.
1. Add a greeting – let the program welcome you in a warm and pleasant way;
2. Have the computer be rude to the user instead of outputting a greeting
3. Duplicate (or triplicate) the greeting to welcome more than one person;
5. Try to remove any of the semicolons and look carefully at the compiler's response; pay attention to where the compiler sees an error – is this where the error really is?
