A History of Computer Programming Languages The first programming languages predate the modern computer. From the first‚ the languages were codes. Herman Hollerith realized that he could encode information on punch cards when he observed that railroad train conductors would encode the appearance of the ticket holders on the train tickets using the position of punched holes on the tickets. Hollerith then proceeded to encode the 1890 census data on punch cards which he made the same size as the boxes

Chapter 2 Computer programming often shortened to programming‚ scripting‚ or coding is the process of designing‚ writing‚ testing‚ debugging‚ and maintaining the source code of computer programs. This source code is written in one or more programming languages (such as Java‚ C++‚ C#‚ Python‚ etc.). The purpose of programming is to create a set of instructions that computers use to perform specific operations or to exhibit desired behaviors. The process of writing source code often requires expertise

Coefficient of Linear Expansion Introduction With few exceptions materials expand somewhat when heated through a temperature range that does not produce a change in phase (i.e. melting‚ freezing‚ boiling etc.). The added heat increases the average amplitude of vibration of the atoms in the material‚ which increases the average separation between the atoms. Although this effect is small‚ it is very important in any application that involves using different materials in an environment where they

days‚ programming languages are becoming more and more general and all-purpose‚ but they still have their specializations‚ and each language has its disadvantages and advantages. Languages can generally be divided into a few basic types‚ though many languages support more than one programming style. This following list isn’t all inclusive or as fine-grained as possible‚ but it brings out some of the basic design decisions behind languages. Language Types • Procedural The programming style

Programming Paradigms Programming languages • A Programming language is a notational system for describing tasks/computations in a machine and human readable form. • Most computer languages are designed to facilitate certain operations and not others: numerical computation‚ or text manipulation‚ or I/O. • More broadly‚ a computer language typically embodies a particular programming paradigm. Characteristics of a programming language: Every language has syntax and semantics: • Syntax: The syntax

CONCEPTS OF PROGRAMING LANGUAGES (COMPUTER SCIENCE 7) PRELIMINARIES Reasons for Studying Concepts of Programming Languages 1. Increased capacity to express ideas – People with limited grasp of natural language are limited in the complexity of their thoughts‚ it is difficult for people to conceptualize structure that they cannot describe‚ verbally or in writing. Programmers in the process of developing software encounter the same constraint. Programmers can increase the range of their software-development
