Program Design
Lab #6• You are presented with six exercises where you have to fill-in-the-blanks.
For each exercise you are presented with a flowchart with some blank boxes, and on the following page a number of potential answers are provided, including the correct answers.
• In the Word document you have all your labs and tutorials in: PROGRAM-DESIGN-PORTFOLIO.DOC (or .DOCX)• add in the screengrabs from this. Now e-mail your document to
[email protected] with a subject heading of PROGRAM DESIGN LAB #6 and in the message of your e-mail please let me know your full name, your student number, the name of your programme, the programme code, the name of the module, the year you are in (first year), and your assignment.
• PLEASE NOTE: If you do not have the correct subject heading on your e-mail, or the correct filename, your submission WILL be rejected.

Exercise #1
• We want to create a flowchart that prints out double the number of the inputted value.
• On the next slide is a flowchart with some blacked out boxes.
• On the following slide is a number of potential boxes you could use to correctly implement the algorithm.
• Copy and paste the boxes into the flowchart.

Read in C B = A + 2 Print C
• Pick the appropriate three of the following boxes that describe the algorithm as described.
• Copy and paste them into the previous slide.
Exercise #2
• We want to create a flowchart that reads in a number, and checks if it is odd or even.
• On the next slide is a flowchart with some blacked out boxes.
• On the following slide is a number of potential boxes you could use to correctly implement the algorithm.
• Copy and paste the boxes into the flowchart.

• Pick the appropriate three of the following boxes that describe the algorithm as described.
• Copy and paste them into the previous slide.
Exercise #3
• We want to create a flowchart that prints out the biggest of three inputted numbers.
• On the next slide is a flowchart with some blacked out boxes.
• On the following slide is a number of potential boxes you could use to correctly implement the algorithm.
• Copy and paste the boxes into the flowchart.

Exercise #4
• We want to create a flowchart that prints out the word “Honour” is the number input is 70, if the number is less than 40 print out the word “Fail”, otherwise print out the word “Pass”.
• On the next slide is a flowchart with some blacked out boxes.
• On the following slide is a number of potential boxes you could use to correctly implement the algorithm.
• Copy and paste the boxes into the flowchart.

• Pick the appropriate three of the following boxes that describe the algorithm as described.
• Copy and paste them into the previous slide.
Exercise #5
• We want to create a flowchart that prints out the average value of five numbers input in.
• On the next slide is a flowchart with some blacked out boxes.
• On the following slide is a number of potential boxes you could use to correctly implement the algorithm.
• Copy and paste the boxes into the flowchart.

• Pick the appropriate three of the following boxes that describe the algorithm as described.
• Copy and paste them into the previous slide.
Exercise #6
• We want to create a flowchart that allows a user to input a number and the program checks if that number is an element in an array, if it is we print “Found”, if not we print “Not Found”.
• On the next slide is a flowchart with some blacked out boxes.
• On the following slide is a number of potential boxes you could use to correctly implement the algorithm.
