Description

Workshop 3 (out of 10 marks – 4% of your final grade)

In this workshop, you will code a C-language program that analyzes data logically.

LEARNING OUTCOMES
Upon successful completion of this workshop, you will have demonstrated the abilities:
• to create a simple interactive program
• to code a decision using a selection construct
• to code repetitive logic using an iteration construct
• to nest a logical block within another logical block

SUBMISSION POLICY
All your work (all the files you create or modify) must contain your name, Seneca email and student number.
You are responsible to back up your work regularly.

Late submission penalties:
– In-lab portion submitted late, with at-home portion: 0 for in-lab. Maximum of 70/70 for at-home and reflection
– If any of in-lab, at-home or reflection portions is missing the mark will be zero.

IN-LAB: (30%)
Download or clone workshop 3 (WS03) from https://github.com/Seneca-144100/IPCWorkshops
Code a program in temps.c that does the following:
1- Before the declaration of main define NUMS as 3: #define NUMS 3

2- Print the title of the application.

>—=== IPC Temperature Analyzer ===—<

3- Using a for loop, prompt the user to enter the high and low values for each of NUMS days. The values entered must be between -40 and 40, and high must be greater than low.

Print the following messages:
>Enter the high value for day 1: < (or day 2, or day 3) * Read the high value.

>Enter the low value for day 1: < (or day 2, or day 3) * Read the low value.

4- Use a nested while (or do-while) loop to analyze the results, high must be greater than low, high must be less than 41, low must be greater than -41

*If any entry is incorrect, prompt the user to enter again until the entries pass the tests:

> Incorrect values, temperatures must be in the range -40 to 40, high must be greater than low. <

Then prompt again for the high and low temperatures for the day.

5- When the user has correctly entered the high and low temperatures, add them to variables that will store the total high and total low temperatures for NUMS days.

6- When the loop finishes calculate the average (mean) temperature for NUMS days and display:

> The average (mean) temperature was: — <

OUTPUT EXAMPLE WITH ERRORS HANDLED (use this data for submission)
—=== IPC Temperature Analyzer ===—
Enter the high value for day 1: 8

Enter the low value for day 1: -2

Enter the high value for day 2: 41

Enter the low value for day 2: -4

Incorrect values, temperatures must be in the range -40 to 40, high must be greater than low.

Enter the high value for day 2: 9

Enter the low value for day 2: -4
Enter the high value for day 3: 5

Enter the low value for day 3: 11

Incorrect values, temperatures must be in the range -40 to 40, high must be greater than low.

Enter the high value for day 3: 11

Enter the low value for day 3: 5

The average (mean) temperature was: 4.50

IN_LAB SUBMISSION:
To test and demonstrate execution of your program use the same data as the output example above.
If not on matrix already, upload your temps.c to your matrix account. Compile and run your code and make sure everything works properly.
Then run the following script from your account: (replace profname.proflastname with your professors Seneca userid)

~profname.proflastname/submit 144_w3_lab <ENTER>
and follow the instructions.

Please Note
• A successful submission does not guarantee full credit for this workshop.

AT_HOME: (30%)
After completing the in_lab section, upgrade temps.c to
• process a 4-day period using a single change to your in_lab code
• display the highest temperature, and on which day it occurred • display the lowest temperature, and on which day it occurred • calculate and display the mean temperature for the 4-day period.

OUTPUT EXAMPLE
—=== IPC Temperature Analyzer ===— Enter the high value for day 1: 8

Enter the low value for day 1: -2

Enter the high value for day 2: 9
Enter the low value for day 2: -4

Enter the high value for day 3: 11

Enter the low value for day 3: 5

Enter the high value for day 4: 10

Enter the low value for day 4: 3

The average (mean) temperature was: 5.00
The highest temperature was 11, on day 3
The lowest temperature was -4, on day 2

AT-HOME REFLECTION (40%)
Please provide brief answers to the following questions in a text file named reflect.txt.
1) Name all the iteration constructs.
2) In two or three sentences explain the difference between a “do while” and a
“while” loop?
3) In two or three sentences explain what is meant by the term conditional expression?
Note: when completing the workshop reflection it is a violation of academic policy to cut and paste content from the course notes or any other published source, or to copy the work of another student.

AT_HOME SUBMISSION:
To test and demonstrate execution of your program use the same data as the output example above… (8, -2, 9, -4, 11, 5, 10, 3)
If not on matrix already, upload your temps.c and reflect.txt to your matrix account. Compile and run your code and make sure everything works properly.
Then run the following script from your account: (replace profname.proflastname with your professors Seneca userid)

~profname.proflastname/submit 144_w3_home <ENTER>
and follow the instructions.
