Problem 2. (Playing the Waltz) Write a program called playwaltz.py that accepts from standard input, a sequence of 32
integers representing the 32 measures of a waltz, and plays the waltz to standard audio. Before playing any audio, your
program must check if the inputs are correct, and if they are not, must call sys.exit (message) to exit the program with an
appropriate error message. The following errors must be handled:
• If the number of measures is not 32, exit with the message "A waltz must contain exactly 32 measures".
• If a minuet measure is not from [1,176], exit with the message "A minuet measure must be from [1, 176]".
• If a trio measure is not from [1,96], exit with the message "A trio measure must be from [1, 96]".
- "/vorkspace/project3
$ python3 generatewaltz.py < data/mozart.txt | python3 playwaltz. py
Directions:
• Read the waltz measures from standard input into a 1D list.
• Handle the input errors described above.
• Play each of the first 16 minuet measures by…

3. Entertaining the Boredby CodeChum Admin
We're now in the middle of our tour but I see these two guys getting bored. I see that their level of engagement is getting low.
Luckily, I remember that I'm good at cheering up. Oh wait, the last time I cheered someone up was a long time ago. Please help me learn how to cheer people up again.
Instructions:
In the code editor, you are provided with the main() function that asks the user for 2 double numbers which represents the engagement levels of the two bored guys and the passes the address of those 2 double numbers to the function call for the function, cheerUp().Your task is to implement the function definition of the cheerUp() function. The cheerUp() function should update the values passed by multiplying each of them by 3.Do not edit anything in the main() function.Input

We have a house with 3 rooms.We need the user to enter 1 integer as the window number, 2 doubles as depth and width of the room, 1 double as the useless area, 1 boolean as the door's opening direction (e.g. 0 is outward).Program will compute and print the air condition as a string and the total useful area of the house as a double.
Calculating the air condition: Name it air_c. Divide the useful area by the window number. If air_c >20, output "bad". If air_c <11 output "good". If 11<=air_c<=20, output "ideal".
Attention: If the window number is 0, air condition is bad.
Calculating the useful area of room: Width*Depth-(useless area)if the door is inward;Width*Depth-(useless area)-0.8The worst air condition of the 3 is the final air condition of house.

A national medical testing laboratory wants a new computer system to analyze its test results. The system must be capable of processing each day's results as well as retrieving and outputting a printed report of all results meeting certain criteria, such as all results for a particular doctor or for hospitals in a certain state. Determine three or four major program units into which this system could be separated. (Hint: One possible program unit is "Prepare Daily Results" to create each day's reports.) b. Suppose someone enters incorrect data for a test result, and the error is discovered after the system has entered and stored the data. What program unit is needed to cor- rect this problem?

On the new screen, the user will then be greeted "Welcome, <firstname>! (i.e. Welcome, Louie!)" The program will then ask for the prelim grade, midterm grade and final grade of the student. The program should only accept grades 100 and below. After getting the three grades, the program should compute for the semestral grade.

- (Gender Neutrality) Write the steps of a manual procedure to process a text paragraph and replace gender-specific words with gender-neutral ones. Assuming you’ve been given a list of gender-specific words and their gender-neutral replacements (e.g., replace “wife” or “husband” with “spouse,” replace “man” or “woman” with “person,” replace “daughter” or “son” with “child,” and so on), explain the procedure you’d use to read through a paragraph of text and manually perform these replacements. How might your procedure generate a strange term like “woperchild” and how might you modify your procedure to avoid this possibility? In Chapter 3, you’ll learn that a more formal computing term for “procedure” is “algorithm,” and that an algorithm specifies the steps to be performed and the order in which to perform them.arrow_forward(Software quality engineering)Derive the test cases using equivalent partitioning.arrow_forward(QUESTION) Using the required programming language (python, matlab, etc.) plot the variation of pressure on the piston surface as a function of time until the piston moves 9 m, with the help of the following commands below.

Instructions: In the code editor, you are provided with a code in the main() which has 12 printf's. Each printf prints a month with its corresponding value. For this program, January is 1, February is 2, March is 3, and so on. When you run the initial code, you will encounter errors because these month names that have been printed don't exist yet.Your task is to create an enum data type which contains these month names as values so that when we run the code, there will be no more error.Do not edit anything in the main().

Two odometer readings should be inputted, one reading is before you fill up the gas tank, and the second reading is when you refill the gas tank. The third input is the quantity of gallons of gasoline purchased when the gas tank is refilled.
