/* 6.914, Example 0.10

We covered the following data types in class: color, int, and float.
Colors are of the following form:
  color colorName = color(redValue, greenValue, blueValue);

ints and floats are integers and floating-point decimal numbers, respectively.
They are declared like this:
  int x;
  float y;
... and assigned value like this:
  x = 5;
  y = 8;
  
If you declare a value in the global environment (outside of the setup()
or draw() methods) you will be able to access it (= assign its value and edit
its value) from all your methods.

Do not declare variables more than once!

color myColor;
int firstNum = 5;
float secondNum;


void setup(){
  myColor = color(255, 0, 0);
}

void draw(){
  background(myColor); // we use myColor, assigned in setup()
  secondNum = firstNum + 3; // secondNum will have a value of 8
}
