pseudocode and flowchart examples pdf

These are the same problems discussed in section 3.1 using flow charts – both methods are acceptable ways of representing an algorithm. To read the flow chart: • Start at the “Start” block, and follow its arrow down to the “Decision” block. Until all players except one have dropped out. Houses = 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. Example 6: Write pseudo code that will perform the following. The end of the loop is marked by ENDWHILE. a) Read in 5 separate numbers. Since there is a use of the loopcounter to succeed to the next element in the array the for loop is vital. Algorithm and flowchart are the powerful tools for learning programming. When the touch sensor is pressed the motors stop and the program ends. – 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 Algorithm Flowchart And Pseudocode Examples Pdf Algorithms and flowcharts are two different tools used for creating new programs, especially in computer programming. Repeat Call Procedure Monopoly_Move for next player. An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way. 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. Each house owner must pay tax based on the value of the house. 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. 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. Decide which player goes first. What statement do we execute when the loop is over? Pseudocode Input the width (W) and Length (L) of a rectangle Calculate the area (A) by multiplying L with W Print A Sample Pseudocode . Decide if this player must drop out. Example 4: Write pseudo code to print all multiples of 5 between 1 and 100 (including both 1 and 100). 2 Writing algorithms using pseudocode The following five examples use the above pseudocode terms. 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. An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way. Example 1: An algorithm that asks for a … Example 3 Write an algorithm and draw a flowchart that will read the two sides of a rectangle and calculate its area. The one that follows the ENDWHILE. b) Calculate the average of the five numbers. 2.1 Example 1 A town contains 5000 houses. # Before specifying our language formally, we'll look at some examples and discuss a few concepts and definitions that will be used below. 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. pseudocode, as well as flowcharts, which are another way of describing algorithms.
