66. OCR GCSE (J277) 2.2 Data types and casting
About this video
OCR J277 Specification Reference - Section 2.2
Through the example of a “beat that dice” game, this video explains how variables are stored in memory and how their data type can be changed using keywords for casting. At the end of the course, it is recommended to watch the videos in 2.6 Data representation to understand how numbers and characters are stored in computer systems, and therefore why casting becomes necessary in programming.
Don't forget, whenever the blue note icon appears in the corner of the screen, that is your cue to take notes about the content being shown on the current slide.
