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:

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

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

What is sequential flow of a program? A sequential slow is a series of consecutive statements which is executed in the order that they instructed. The computer only operates on sequential code‚ one statement after the next‚ until it encounters a decision structure‚ loop structure‚ or a submodule. After the decision‚ loop‚ or instructions are completed‚ the next statement in sequence will be executed. What is branching within a program? Branching is similar to a fork like structure. It basically

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.

Arrays: Lists and Tables Although the value of a variable may change during execution of a program‚ in all our programs so far‚ a single value has been associated with each variable name at any given time. In this chapter‚ we will discuss the concept of an array—a collection of variables of the same type and referenced by the same name. We will discuss one-dimensional arrays (lists) at length and focus briefly on twodimensional arrays (tables). You will learn how to set up and use arrays to accomplish

Progamming concepts | | Week 1 Pseudocode Statement ReviewThere are 4 types of pseudocode statements that we learn in Week 1:DeclareYou use Declare to tell the computer the names of variables and the types of variables. The syntax is:Declare variablename as type A variable name must begin with a letter‚ can include letters‚ numbers and the underscore. Spaces are not allowed. The variable type is based on the data that the variable will hold. For example‚ if the variable stores a name‚ then
