Variables in C#
A variable is a storage holder, and is essential for the programmer.
In C#, a variable is declared like this:

Syntax: 
<data type> <name>;


An example could look like this: 
string name;


You can also control the visibility of a variable like this, 

<visibility> <data type> <name> = <value>; 


public string name; //Visible to all
private string name; //Not visible to all
