a) Read in 5 separate numbers. Page 1 of 13 Computer Science 2210 (Notes) Chapter: 2.1 Algorithm design and problem-solving Topic: 2.1.2 Pseudocode and flowcharts U Introduction to Pseudocode This section covers the use of pseudocode in the production of algorithms. • Flowcharts: – graphical description of the flow of processing steps – not used very often, somewhat old-fashioned. These are the same problems discussed in section 3.1 using flow charts – both methods are acceptable ways of representing an algorithm. The end of the loop is marked by ENDWHILE. 2 Writing algorithms using pseudocode The following five examples use the above pseudocode terms. The one that follows the ENDWHILE. To read the flow chart: • Start at the “Start” block, and follow its arrow down to the “Decision” block. Houses An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way. pseudocode: count = 0 WHILE count < 10 ADD 1 to count WRITE count ENDWHILE WRITE “The end” no Notice that the connector and test at the top of the loop in the flowchart become the WHILE stmt in pseudocode. Algorithm and flowcharts helps to clarify all the steps for solving the problem. Pseudocode Example: This is the pseudocode for a Game of Monopoly, including one person's move as a procedure: Main Procedure Monopoly_Game Hand out each player's initial money. Since there is a use of the loopcounter to succeed to the next element in the array the for loop is vital. An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way. Decide if this player must drop out. Example 3 Write an algorithm and draw a flowchart that will read the two sides of a rectangle and calculate its area. pseudocode, as well as flowcharts, which are another way of describing algorithms. Example 5: Write pseudo code that will count all the even numbers up to a user defined stopping point. Pseudo Code Example 4 fill the array with random variables Pseudo Code Example 4 is very concise description of the algorithm and most programmers know how to implement it. b) Calculate the average of the five numbers. When the touch sensor is pressed the motors stop and the program ends. 2.1 Example 1 A town contains 5000 houses. To the right is the flow chart of a program which instructs a robot to run forward as long as its touch sensor is not pressed. Pseudocode Input the width (W) and Length (L) of a rectangle Calculate the area (A) by multiplying L with W Print A Each house owner must pay tax based on the value of the house. Example 6: Write pseudo code that will perform the following. # Before specifying our language formally, we'll look at some examples and discuss a few concepts and definitions that will be used below. Repeat Call Procedure Monopoly_Move for next player. Algorithm and flowchart are the powerful tools for learning programming. Algorithm Flowchart And Pseudocode Examples Pdf Algorithms and flowcharts are two different tools used for creating new programs, especially in computer programming. ALGORITHM Sample. What statement do we execute when the loop is over? – however, sometimes useful to describe the overall structure of an application • Pseudocode: – artificial language based on • vocabulary (set of keywords) • syntax (set of rules used to construct the language’s Decide which player goes first. Until all players except one have dropped out. Example 4: Write pseudo code to print all multiples of 5 between 1 and 100 (including both 1 and 100). Example 1: An algorithm that asks for a … Sample Pseudocode . GET Data . Where N! = 1 * 2 * 3 *...* N. This flowchart represents a "loop and a half" — a situation discussed in introductory programming textbooks that requires either a duplication of a component (to be both inside and outside the loop) or the component to be put inside a branch in the loop.
