Unformatted text preview: ECE 3090 Software for Engineering Systems Dr. Ayanna Howard School of Electrical and Computer Engineering Georgia Institute of Technology Intro Lecture 2 Adapted from “Brief Version of Starting Out with C++” Why Program? Computer – programmable machine designed to follow instructions Program – instructions in computer memory to make it do something Programmer – person who writes instructions (programs) to make computer perform a task SO, without programmers, no programs; without programs, a computer cannot do anything 3 Adapted from “Brief Version of Starting Out with C++” Programs and Programming Languages – Categories of software: – Operating system: programs that manage the computer hardware and the programs that run on them. Examples : Windows, UNIX, Linux – Application software: programs that provide services to the user. Examples : word processing, games, programs to solve specific problems – A program is a set of instructions that the computer follows to perform a task – We start with an algorithm , which is a set of well-defined steps. 4 Adapted from “Brief Version of Starting Out with C++” Example Algorithm for Calculating Gross Pay Write the steps necessary to calculate gross pay for an electrical engineering student working during the summer. 5 Adapted from “Brief Version of Starting Out with C++” From a High-level Program to an Executable File – Although the previous algorithm defines the steps for calculating the gross pay, it is not ready to be executed on the computer. – The computer only executes machine language instructions. a) Create file containing the program with a text editor. b) Run preprocessor to convert source file directives to source code program statements....
