/*
Variable Scope
 
 LOCAL: means variable is declared inside a function / method thus is only visible to that
 specific function / method.  Nowhere else
 
 
 GLOBAL: variable is declared at the top and is visible to be used by ALL functions / methods
 -> you can't reuse that variable name anymore
 
 
 Variable Types
 
 int:  INTEGER thats numbers both positive and negative, but NO decimals
 float: FLOAT PRECISION decimal numbers
 String: words and sentences and such, can also hold numbers but they will be treated like words
 boolean: a TRUE or FALSE
 
When you declare a variable, stating the type specifies the size of memory needed to store it.
Example, boolean true or false data takes less room than big numbers or entire words
 
 ASSIGNMENT
 
 make a sketch, size it 640 by 480
 declare 3 integers and 3 strings
 make those all global
 display them in a screen, colours are whatever
 
 make 3 more variables of any type but them local to the draw function
 again display the things
 
 call you sketch:  program1

  rect(0, 0, 640, 480); //fill a rectangle the ize of the screen

  fill(100, 100, 100); //Gat another color
  text("testing teh words" + white, 200, 200); //write words
}


//Runs when the mouse is pressed
void mousePressed() {
  println("this is other thing: " + white); //Accesses the global variable 'white'
