03. C Programming for IA: Pointers, Arrays, Casting and Endianness

In this fourth video in my series on C programming for image analysis (CPIA), I cover the important key topics of variables that store memory addresses (pointers), compound variables of a single data type (arrays), casting, endianness and byte-swapping. Source code examples are provided and explained. These tutorials are designed for mature students without prior experience in programming, computer science, maths or engineering.
