The Payroll Department keeps a list of employee information for each pay period in a text file. Write a program that inputs a filename from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular format with the appropriate header. Each line should contain an employee’s name, the hours worked, and the wages paid for that period. The wages paid are equal to the hourly wage * hours worked + tips. Use the sample data in this payroll sample.txt | | | V
Suppose that the file inData.txt, data set 1, contains the following data: Giselle Robinson Accounting 5600 5 30 450 9 75 1.5 The first line contains a person’s first name, last name, and the department the person works in. In the second line, the first number represents the monthly gross salary, the bonus (as a percent), and the taxes (as a percent). The third line contains the distance traveled and the traveling time. The fourth line contains the number of coffee cups sold and the cost of each coffee cup. Write statements so that after the program executes, the contents of the file outData.txt are as shown below. If necessary, declare additional variables. Your statements should be general enough so that if the content of the input file changes and the program is run again (without editing and recompiling), it outputs the appropriate results. Name: Giselle Robinson, Department: Accounting Monthly Gross Salary: $5600.00, Monthly Bonus: 5.00%, Taxes: 30.00% Paycheck: $4116.00…
Given the file name of a .tsv file read from user input containing student names and the respective course assignment grades, complete a program that performs the following tasks: Read the input file as a pandas dataframe. Output the students' names and grades in descending order of Finals scores. Output each assignment's max score. Output the median and average of each assignment's scores. Output the standard deviation of each assignment's scores. NOTES: Steps 3 through 5 should only require one function for each step. Ex. Finding the max of each assignment uses max() Append .to_string() to the end of the function call in order to silence an extraneous line that occurs at the end of the output. For steps 3, 4, and 5, the functions used will require the parameter numeric_only=True to be passed to specify that only numbers will be calculated (as the input file contains strings for student names). Input and Output Example NOTE: Download StudentInfo.tsv to view the contents of the file.

Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row and…

The 2 pictures are the beginning of the lab. The below is for part 2. read_file(0, clear_file); // Read in a file with of unknown length, getting the length from the file read. clear_file is a string containing the path to the clear text file. This function returns a char array created with memory allocation. read_file(len, clear_file); // Where len > zero, reads len chars from a file. clear_file is a string containing the path to the clear text file. This function returns a char array created with memory allocation. write_file(0, key, key_file); // Writes a string to file until the \0 char is reached. key is the string of random chars and key_file is a string containing the path of the text file. write_file(len, cipher, cipher_file); // Where len > zero, writes len chars to a file. cipher is the cipher string of chars and cipher_file is a string containing the path of the text file.

Time remaining: 00:09:44 Computer Science A file containing data about some students' options regarding a set of optional subjects is given. The file is available in the resources section of laboratory 2. The file contains 10,000 lines, each student having 2 consecutive lines from the file. On the first line of the two is the name of the student and on the second is a series of 4 codes representing the same number of options. Knowing that there are a total of 5,000 students and that no student's name is longer than 35 characters, it is required: · Read the data in the file in an array of 5,000 elements of the form <name, optional1, optional2, optional3, optional4> · Knowing that the students are sorted alphabetically by name, to apply an optimal search algorithm, from those studied in this laboratory and to count the number of comparisons to find the student MATEI STEFAN. · Apply the linear search algorithm to locate all students who have chosen a particular option, given…
