Simple Code Practice

// Intial, un-sorted array

const int ARRAY_LENGTH = 5;

int array[ARRAY_LENGTH] = { 3, 1, 2, 5, 4 };

// SET-UP Function (runs first and only once)

void setup() {

  // Start serial communication of 9600 bps (bits per second)

  Serial.begin(9600);

  // note: if you use a physical Arduino, ensure that your Serial Monitor is set to the same baud rate, or you might get weird output!

  // One second delay before starting your code

  delay(1000);

  // YOUR CODE TO SORT THE ARRAY

  // note: without your code, this program will just print out the array un-sorted!

  // Print array to Serial Monitor (if your sorting code is written before this line, then the printed array will be sorted)

  // note: printing is this code does NOT involve any physical printing, just means displaying output to your screen via Serial Monitor

  for (int index = 0; index < ARRAY_LENGTH; index++) {

    // "index" will increment by 1 from 0 while it is less than "ARRAY_LENGTH", so 0->1->2->3->4

    Serial.println(array[index]);  // print to Serial Monitor number at this index of the array

    // note: the "ln" in the command above indicates a new line, meaning each number will be printed on a new line

  }

}

// LOOP Function (runs second and loops forever)

void loop() {

  // we do not need anything to loop!

}
