During this lesson, students start to see the data structure they will use to store their images, towards finding a solution to this unit's Grand Challenge. Students are introduced to two-dimensional arrays and vector classes. Then they are guided to see that a vector class is the most efficient way of storing the data for their images. Grand Challenge: To write a program to simulate peripheral vision by merging two images.
Data of all kinds is often stored in arrays to make it easier to work with on a large scale. Arrays are often used in computer programming as a way to store and manipulate data. An example of this data could be the pixels in a two-dimensional image, which is the focus of this lesson. Computer science engineers also know that arrays also make it easier to retrieve stored data.
After this lesson, students should be able to:
- Initialize a two-dimensional array.
- Initialize a new instance of a vector class.
- Store RGB values in a vector.
- Read data from vector and write to a new image.
- Apply new knowledge to the unit's Grand Challenge question.

- Standard 5.0 - The student will write and document an executable program in C++ Programming Language.
