This includes submitted homework, labs, and in class assignments. You may not use any other electronic reference material. 4. With about ~10 minutes remaining, you must wrap up what you are doing, and upload your source code to the Blackboard Assignment Manager. 5. Take a deep breath - you can do it! Problem & Instructions: The salinity of the water in the ocean is a function of the water temperature, ocean depth and current speed. Additionally, the salinity is highly dependent upon the particular ocean that is under consideration. Your task today will be to write a program that will serve as an ocean salinity calculator. Given the water temperature T in degrees Kelvin, ocean depth D in meters and current speed C in meters per second, the water salinity S in parts-per-hundred (pph) is given as log 10 10(+D+1)T/223.1 166 S = 33 C+1 + 3.0 where R is the reference salinity for a particular body of water (i.e., a particular ocean). Your task today is to create a program to compute S in pph. You are to query the user to enter the water temperature T in degrees Celsius (you will need to convert 7 temporarily to degrees Kelvin to compute S), ocean depth D in meters and current speed C in meters per second. Assume that the user enters the data correctly and in the correct unit. Furthermore, you are to have the user enter the name of the ocean and a single letter (N or S) to indicate the hemisphere. Follow these detailed instructions: Tier 1 Requirements (Minimum Deliverables to receive a 'C' on the exam): 1. Pay attention to the compiler messages as you go along. Also turn it in on time. Penalties are as follows: Each type of error Each type of warning Each minute late -10 -5 -10 2. (15 pts) Start from the provided template code. Include any additional libraries that are necessary. Use good formatting and style. Match your output to the examples given. 3.

(5 pts) Prompt (best judgment) user and scan in the ocean name. 9. (5 pts) Prompt (best judgment) user and scan in the hemisphere (N/S). 10. (5 pts) Print out the hemisphere and ocean name as shown. Tier 3 Requirements (Minimum Deliverables to receive an 'A' on the exam): 11. (5 pts) Create a function to calculate the salinity using the given equation. 12. (5 pts) Use the function to calculate the salinity. 13. (5 pts) Display the salinity and output as shown. EGR 104 Test set #3: Input: Practice Practicum 1 31.5 2.75 12.9875 Pacific N Output: Based on the following data: temperature of 31.5 degrees C (304.65 K), depth of 2.75 m, and current speed of 12.9875 m/s in the N Pacific Ocean, the water salinity is 4.579 parts-per-hundred. Example Input/Output: Below are example test cases with expected output in order to help you validate your code. The input data is listed as T, D, C followed by the ocean name and hemisphere.
