3. For loops

Going backwards in an array -> More than or equal to zero, decrement the variable, start array at length - 1

Nested for loops -> Everytime you have 2 for loops, the outer one is run once and the inner is run all the way through

4. Loops

Array indexes account for zero

When finding out which index is greatest, use a for loop and compare the indexes
int[] example = {5, 7, 3, 9, 20, 4};

void setup() {
  int maxIndex = 0;
  for (int i = 0; i < example.length; i++) {
    if (example[i] > example[maxIndex]) {
      maxIndex = i;
    }
  }
}

void draw() {

}


int[] example = {60, 90, 50, 30, 60, 100};
int numPass = 0;
int numFail = 0;

void setup() {
  int maxIndex = 0;
  for (int i = 0; i < example.length; i++) {
    if (example[i] >= 70) {
      numPass++;
    }
    else {
      numPass--;
    }
  }
}
