Overview
A 2D Array (two-dimensional array ) is used to store and retrieve information with two dimensions, like a matrix. It has rows and columns.
Single-dimensional array example:
A single-dimensional array has one index to identify Alice’s subject.
Now, let’s say we are building a flowchart for Alice’s class, which has many students. We want to capture all students’ marks. If Alice’s class has n students, we need n single-dimensional arrays for each student.
To identify an element in a two-dimensional array, we need two parameters: one to identify the row and one to identify the column. In RAPTOR, they are separated with commas.
For example:
StudentMarks[2,3]
2 identifies the student row
and 3 identifies the subject.
Read Two Dimensional Array
To handle a two-dimensional array in the flowchart, we need two loops: one loop to track the row and another to track the column.
