1. using System;
namespace Demo01 {
class Program
static void Main(string[] args)
Console.WriteLine("Hello world"); }

2. using System;
namespace Demo01 {
class Program
static void Main(string[] args)
string name = "world";
Console.WriteLine("Hello " + name); }

3. String
Is a type
Contains text

4. using System;
namespace Demo01 {
class Program
static void Main(string[] args)
string name = "world";
Console.WriteLine("Hello " + name);
name = "Loek"; }

5. using System;
namespace Demo01 {
class Program
static void Main(string[] args)
string name = "world";
Console.WriteLine("Hello " + name);
name = "Loek";
name = "Leo"; }

6. Integer
Is a type
Contains numbers

7. using System;
namespace Demo01 {
class Program
static void Main(string[] args)
string name = "world";
Console.WriteLine("Hello " + name);
name = "Loek";
int year = 2017;
Console.WriteLine("Hello " + name + " this year is " + year); }

8. using System;
namespace Demo01 {
class Program
static void Main(string[] args)
string name = "world";
Console.WriteLine("Hello " + name);
name = "Loek";
int year = 2017;
Console.WriteLine("Hello " + name + " this year is " + year);
year = year + 1; }

9. Loops
Made to repeat things

10. for (int i = 0; i < 10; i++){
Console.WriteLine("Hello " + name + " this year is " + year + i); }

11. Order is important. Just like in Math:
for (int i = 0; i < 10; i++) {
Console.WriteLine("Hello " + name + " this year is " + (year + i)); }
Order is important. Just like in Math: ^ * / + -
