Programming Languages Memory Allocation, Garbage Collection CSCI.GA-2110-003 Fall 2020 Dynamic memory management For most languages, the amount of memory used by a program cannot be determined at compile time ■ earlier versions of FORTRAN are exceptions! Some features that require dynamic memory allocation: ■ recursion ■ pointers, explicit allocation (e.g., new) ■ higher order functions […]
Programming Languages OOP CSCI-GA.2110-003 Fall 2020 What is OOP? (part I) The object idea: ■ bundling of data (data members) and operations (methods) on that data ■ restricting access to the data An object contains: ■ data members : arranged as a set of named fields ■ methods : routines which take the object they
Control in Sequential Languages Mitchell Chapter 8 Topics – “structured” jumps that may return a value • Exceptions – dynamic scoping of exception handler • Continuations – Function representing the rest of the program – Generalized form of tail recursion • Control of evaluation order (force and delay) – Can increase efficiency – Call-by-need parameter

Introduction and Definitions Most programming languages describe computation in an imperative style. Some definitions from Wikipedia: Imperative Programming Imperative programs define sequences of commands for the computer to perform. A programming paradigm that describes computation in terms of statements that change a program state Declarative programming Declarative programs express what the program
