1. Exam Points 2. Knowledge Points (1) Traverse 2D arrays : for Loops Nested iteration/loop statemen

A 2D array is an array of arrays. It uses two indexes.

One 2D array is an array of arrays. You may say that a 2D array consists of multiple 1D arrays.

The way statements are sequenced and combined in a program determines the computed result.

Iteration Iteration is a repeating portion of an algorithm.

Nested conditional statements consist of conditional statements within conditional statements.

Conditional Statements Selection determines which parts of an algorithm will be executed.

Boolean Expressions, relational operators and logical operators.
