Algorithm – Representation (Primitives) Algorithm Representation ü Student of origami would have little difficult to follow the instructions as compared to other students. 5

Algorithm – Representation (Primitives) Primitive ü Computer Science establishes set of building blocks from which algorithm can be constructed, such building blocks are known as primitive. 6

Algorithm – Representation (Primitives) Programming Language ü A collection of primitives along with a collection of rules stating how the primitives can be combined to represent more complex ideas constitutes a programming language. 7

Algorithm – Representation (Primitives) Primitives ü Each primitive has its own syntax (symbol) and semantics (meaning) 8

Algorithm – Representation (Primitives) Origami Primitives 9

Algorithm – Representation (Primitives) Representation in machine level ü Machine level representation is ultimately required. ü It is tedious ü Therefore, high level programming language have been built, mapping primitives to machine level instructions 10
