cisco Cisco Networking Academy Med Wide Open Lab-Create a Process Flowchart Objectives Part 1: Recognize Symbols Used in a Flowchart and List Logical Process to Solve a Problerm Part 2: Draw the Flowchart to lillustrate the Problem Solving Process Background Flowcharts are diagrams used to represent processes or workflows. Using different shapes, boxes, and connecting arrows, a flawchart represents the solution flow to a given problem. Flawcharts are commonly used to represent programs, algorithms, or any ordered process in various disciplines. Flawcharts are typically created prior to starting a process or writing an application in arder to verity and catch potentiai logic flows toward the solution before it is developed and implemented. Flowcharts can be hand drawn or created using a number of packages including Microsoft Office products, LibreOffice, GoogleDocs, and various web applicatians such as hittpe lwww.crawi Some of the most common flowchart symbols that used for programming are shown in the diagram along with their intended purpose for the symbol.

The process developed is represented in a flowchart. Using the flowchart, we can check and verify the logical process toward the problem.

Lab - Mapping the Internet Part 1: List the logical steps required to solve a problem The problem is to develop a process to find a predetermined number. The process can be simple computer game. A player is asked to think about an integer nunm will use the bisection method to find the number programmed as a ber between 0 and 128, The progranm Step 1: List the steps needed to solve the problem. a. Ask the player to think about an integer number between 0 and 128. b. Set a as the lower end, b as the high end, and t as the time of calculation c. Set initial values, a 0, b 128, t d. Calculate the average number between a and b. Set it as M. e. Set tst+1 f. Ask the player if M is the correct number: If yes, print The number you thought of is M and I guessed it t tries End the process Else ift#6 If yes, print "1 am sorry that I cannot guess it after 6 attempts. End the process Else Ask the player if M is larger than the correct number If yes, set a M, jump to Step d. Set b M, jump to Step d Cuestions Can the process catch if the number the player has chosen is 0 or 128? Why or why not? If O or 128 cannot be caught, what should be done to correct it? Part 2: Draw the Flowchart Step 1: Use appropriate flowchart symbols for each functions. Because the list of process steps is identified, we can use fowchart symbols to represent each step.

Use a line to link them: a. Start Please think of an integer number between 0 and 128 b. Use a preparation symbol to make initial assignment: a:0, b 128 t-0 c. Use a predefined process symbol to define a process function or routine: M-(a+b)/2 t-t+1 d. Use a decision symbol to represent a condition test: No Yes Is M correct?
