Hi! I am having trouble with this problem:
Each week, the Pickering Trucking Company randomly selects one of its 30 employees to take a drug test. Write an application that determines which employee will be selected each week for the next 52 weeks. Use the Math.random() function to generate an employee number between 1 and 30. After each selection, display the number of the employee to test. Display four employee numbers on each line. It is important to note that if testing is random, some employees will be tested multiple times, and others might never be tested. Run the application several times until you are confident that the selection is random. Save the file as DrugTests.java.
My code is on the photo.
I want to add the text "Week # (insert week number here). Employee # (insert employee number here)" but I have been unsuccessful in my attempts. Any help would be great!
Domino's Time
Function Name: dominosTime()
Parameters: N/A
Returns: None
Description: During the summer, you ordered a lot of food from Domino's. Pizzas are $12, an
order of pasta is $6, and chicken wings are $8. Write a function that asks the user how many
of each food item they would like, and then print a response telling them what their order to-
tal will be. The order total should be an integer.
>>> dominosTime()
How many pizzas do you want? 3
How many orders of pasta do you want? 2
How many orders of chicken wings do you want? 2
By ordering 3 pizzas, 2 orders of pasta, and 2 orders of chicken wings, your
order total comes to $64.
C#
Account numbers sometimes contain a check digit that is the result of a mathematical calculation. The inclusion of the digit in an account number helps ascertain whether the number is a valid one.
Write an application named CheckDigit that asks a user to enter a four-digit account number and determines whether it is a valid number.
The number is valid if the fourth digit is the remainder when the number represented by the first three digits of the four-digit number is divided by 7. For example, 7770 is valid, because 0 is the remainder when 777 is divided by 7.
If the account number is valid, output The account number is valid. If the account number is invalid output Invalid. If the account number is too short or too long output Account number invalid - it must have 4 digits.

- 99 question Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.arrow_forwardA program contains the following function. int cube(int num) {return num * num * num; }Write a statement that passes the value 4 to this function and assigns its return value to the variable result.arrow_forwardThe Problem__: Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions: ⚫ void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered. ⚫ void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores. ⚫int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop. Input Validation: Do not accept test scores lower than 0 or higher than 100. YOU MUST USE THE STATED FUNCTIONS AND COMPLETE Input VALIDATION. **DO NOT use an ARRAY OR GLOBAL VARIABLES!!. you MUST USE function prototyping TEST THE FUNCTION TWICE.…arrow_forward

At different points in the game, you want the user to select to fight, run, or hide from certain enemies. The selection variable must be sent as an argument into the choice() function. The user should enter 1 to fight, 2 to run, or 3 to hide in the main(). The choice() function should print one of the three options. Add an if statement in the choice() function to make the correct selection.arrow_forwardc++ The Seri Kuala Lumpur School auditorium contains 20 rows (numbered 1 through 20) with 30 seats each (numbered 1 through 30). Write an application that allows a user to continuously enter a row and seat request until a sentinel value is entered. If the row or seat number is out of range, issue an error message. Otherwise, determine whether the seat has already been reserved. If so, display an error message. If not, then charge the user $7.50 for a ticket and display a running total of the user’s purchase. When the user enters a sentinel, display the number of seats taken and the number of seats available in the auditorium.arrow_forward

You have to enter the CREDIT for each of the 5 subjects for a Student. GRADE POINT can take any value as given [5,6,7,8,9,10] CREDIT can take any value as given [2,3,4] CREDIT POINT = GRADE POINT * CREDIT CGPA = CREDIT POINT / Sum of the CREDIT values of all the 10 semesters.

Assume further that there are the following int variables, declared and already initialized: acount, bcount, ccount, dcount, fcount. Write a switch statement that increments the appropriate variable (acount, bcount, ccount, etc.) depending on the value of grade. So if grade is 'A' then acount is incremented; if grade is'B' then bcount is incremented, and so on.arrow_forwardC# Language You are tasked with writing a program to process students’ end of semester marks. For each student you must enter into your program the student’s id number (an integer), followed by their mark (an integer out of 100) in 4 courses. A student number of 0 indicates the end of the data. A student moves on to the next semester if the average of their 4 courses is at least 60 (greater than or equal to 60). Write a program to read the data and print, for each student: The student number, the marks obtained in each course, final mark of the student (average of all the marks), their final grade (A,B,C,D or F) and whether or not they move on to the next semester. In addition, after all data entry is completed, print The number of students who move on to the next semester and the number who do not. The student with the highest final mark (ignore the possibility of a tie). Grades are calculated as follows: A = 70 and over, B = 60 (inclusive) -70, C = 50(inclusive)-60 D =…arrow_forward
