40 points

Objectives:

In this lab, you learn to create a Raptor flowchart.

After completing this lab, you will be able to:

• Plan the logic for a solution to a programming problem using multi-alternative selection structure.
• Create a counter loop structures.

Pre-Lab

Do the following activities before doing the lab assignment. 

• Read chapter 3
• Open the "Programming Control Structure"  pdf document. Read the Selection Control from pages 2 to 5.
• Read chapter 4 Repetition Structures - sections 4.1 and 4.2

Problem 1 [10 points]

Diana Lee, a supervisor in a manufacturing company, wants to know which employees have increased their production this year over last year so that she can issue them certificates of commendation and bonuses. Design a Raptor flowchart  for following: 

A program that accepts each worker’s first and last names, this year’s number of units produced, and last year’s number of units produced. Displays the name and a bonus amount. The bonuses will be distributed as follows: 

If this year’s production is greater than last year’s production and this year’s production is:

• 1,000 units or fewer, the bonus is $25
• 1,001 to 3,000 units, the bonus is $50
• 3,001 to 6,000 units, the bonus is $100
• 6,001 units and up, the bonus is $200

Output #1

Enter last name:
Nguyen
Enter first name:
John
Enter this year's units:
3000
Enter last year's units:
4000
Nguyen, John
Bonus is $0.0

Output #2

Enter last name:
Nguyen
Enter first name:
John
Enter this year's units:
900
Enter last year's units:
300
Nguyen, John
Bonus is $25.0

Output #3

Enter last name:
Nguyen
Enter first name:
John
Enter this year's units:
2500
Enter last year's units:
2000
Nguyen, John
Bonus is $50.0

Output #4

Enter last name:
Nguyen
Enter first name:
John
Enter this year's units:
4500
Enter last year's units:
4000
Nguyen, John
Bonus is $100.0

Output #5

Enter last name:
Nguyen
Enter first name:
John
Enter this year's units:
7000
Enter last year's units:
6000
Nguyen, John
Bonus is $200.0

Grading

Name the Raptor flowchart file as lab41.rap. Do not change the file name to any other name. Submit the file to the Beachboard.

Problem 2 [10 points]

Grading

Name the Raptor flowchart file as lab42.py. Do not change the file name to any other name. Submit the file to the Beachboard.

Problem 3 [10 points]

The formula for converting a temperature from Celsius to Fahrenheit is 

                         F =  9.0  C  + 32
                                  5

Create a Raptor flowchart to display a table of the Celsius temperatures from 0 to 15 and their Fahrenheit equivalents. Name the file lab43.rap.

Sample output

Celsius  Fahrenheit

0           32.00
1           33.80
2           35.60
3           37.40
4           39.20
5           41.00
6           42.80
7           44.60
8           46.40
9           48.20
10         50.00
11         51.80
12         53.60
13         55.40
14         57.20
15         59.00

Hints:

1. Display "Celsius        Fahrenheit" using the Raptor output symbol
2. Set the counter variable celsius to 0
3. Insert the Raptor loop structure. The loop condition is celsius <=15.
   If the condition is true, the calculate fahrenheit as fahrenheit = 9.0/5.0 * celsius + 32.
   Display celsius and fahrenheit using the output symbol. 
   celsius + "           " + fahrenheit
   Increment celsius by one  celsius = celsius + 1
4. If the condition is false (No), then end the Raptor flowchart

Grading
