Overloading Subtyping Overloading and Subtyping Christine Rizkallah CSE, UNSW Term 3 2020 1 Overloading Subtyping Motivation Suppose we added Float to MinHS. Ideally, the same functions should be able to work on both Int and Float. 4+6 :: Int 4.3 + 5.1 :: Float Similarly, a numeric literal should take on whatever type is inferred

COMP3161/COMP9164 Supplementary Lecture Notes Imperative Programming Liam O’Connor September 22, 2020 The term imperative refers to programming languages that are defined as a series of commands that manipulate both the external world and internal state. The order in which commands are executed is significant in an imperative language, as the state changes over time. Typically,
