Function Basics
A computer runs a program one line at a time. When a function is run, the computer jumps to where the function is defined and runs the code there, then jumps back to where it left off.
Example 9-1: Roll the Dice
This behavior is illustrated with the rollDice() function written for this example. When a program starts, it runs the code in setup() and then stops. The program takes a detour and runs the code inside rollDice() each time it appears:
void setup() { println("Ready to roll!"); rollDice(20); rollDice(20); rollDice(6); println("Finished."); } void rollDice(int numSides) { int d = 1 + int(random(numSides)); println("Rolling... " + d); }
The two lines of code in rollDice() select a random number between 1 and the number of sides on the dice, and prints that number to the Console. Because the numbers are random, you’ll see different numbers each time the program is run:
