Table-5a Inside Outside

Inside/Outside Loop Experiment - Om Nom Nom Nom

Let's look again at the importance of inside vs. outside of loops.

Loop - power technique to do something a zillion times
For a line of code ...
-inside vs. outside the loop is a huge difference.
Experiment:
Facts: 2000 names (rows) total, 12 names end with "x"
Move this line to various spots: print("nom");
How many "nom" for each "Location N" below.
Enter your guess numbers below
Then we'll try running it

table = new SimpleTable("baby-2010.csv");
// Location 1
print("nom");
for (row: table) {
  // Location 2
  if (row.getField("name").endsWith("x")) {
    print(row);
    // Location 3
  }
}
// Location 4

tablea5-1

Experiment solutions:

  Location 1: 1  (outside the loop, before it)
  Location 2: 2000 (in the loop, not in the if-body)
  Location 3: 12  (in the if-body)
  Location 4: 1  (outside the loop, after it)
