Pseudocode (pronounced SOO-doh-kohd) is a detailed yet readable description of what a computer program or algorithm must do‚ expressed in a formally-styled natural language rather than in a programming language. Pseudocode is sometimes used as a detailed step in the process of developing a program. It allows designers or lead programmers to express the design in great detail and provides programmers a detailed template for the next step of writing code in a specific programming language. Because

Pseudocode: A LATEX Style File for Displaying Algorithms D.L. Kreher Department of Mathematical Sciences Michigan Technological University Houghton‚ MI 49931 kreher@mtu.edu and D.R. Stinson Department of Combinatorics and Optimization University of Waterloo Waterloo ON‚ N2L 3G1 dstinson@uwaterloo.ca 1 Introduction This paper describes a LATEX environment named pseudocode that can be used for describing algorithms in pseudocode form. This is the style used in our textbook Combinatorial Algorithms:

What is Pseudocode First‚ you need to understand that pseudocode is not a programming language. Pseudocode cannot be compiled nor executed on a computer‚ and there is no real formatting or syntax rules. It is simply one step‚ a very important step‚ in producing the final code. The benefit of pseudocode is that it enables the designer to concentrate on the algorithms without worrying about all the syntactic details of a programming language. In fact‚ you can write pseudocode without even knowing

PSEUDOCODE STANDARD Example Pseudocode is a kind of structured english for describing algorithms. It allows the designer to focus on the logic of the algorithm without being distracted by details of language syntax. At the same time‚ the pseudocode needs to be complete. It describe the entire logic of the algorithm so that implementation becomes a rote mechanical task of translating line by line into source code. In general the vocabulary used in the pseudocode should be the vocabulary of

IT104 - Unit 7 Homework and Lab Assignment Unit 7 Homework (from Ch 5) 1.) Describe the difference between pretest loops and posttest loops. 2.) What is a conditioned-controlled loop. 3.) What is a count-controlled loop. 4.) What is an infinite loop. Write the code for an infinite loop. 5.) Design a While loop that lets the user enter a number. The number should be multiplied by 10‚ and the result stored in a variable named product. The loop should stop once product contains a value > 100.

1 FLOWCHARTS PREPARED BY: ANUSHKA NANCOO 2 WHAT IS A FLOWCHART? Maps or graphical representations of a process Illustrates the sequence of operations to be performed to get to the solution of a problem Useful tool for communication 3 USES OF A FLOWCHART To see whether the steps of a process are logical To record the sequence of tasks in a process To uncover problems/miscommunication To define the boundaries of a process Aids in developing a common base knowledge

Solution for Chapter 2 Exercise 5a 5. a. Draw the hierarchy chart and then plan the logic for a program for the sales manager of The Couch Potato Furniture Company. The manager needs a program to determine the profit on any item sold. Input includes the wholesale price and retail price for an item. The output is the item’s profit‚ which is the retail price minus the wholesale price. Use three modules. The main program declares global variables and calls housekeeping‚ detail‚ and end-of-job

Programming – Selection Structure John Doe PRG/211 June 25‚ 2013 GUILLERMO HERNANDEZ Introduction: The purpose of this paper is to provide a simple example of a selection structure that is contained as part of the Programming Solution Proposal I am developing throughout the course of this programming class. The selection structure I chose to make an example of isn’t really inclusive as part of my original programming proposal due in week 5‚ however‚ I devised a very simple

Algorithm The term algorithm is often used to refer to the logic of a program It is a step-by step description of how to arrive at the solution of the given problem. It may be formally defined as a sequence of instructions‚ designed in a manner that‚ if the instructions are executed in the specified sequence‚ the desired results will be obtained. In order to qualify as an algorithm‚ a sequence of instructions must possess the following characteristics: Sample Algorithms 50 Students in a class
