The Payroll Department keeps a list of employee information for each pay period in a text file. The format of each line of the file is the following: <last name> <hours worked> <hourly wage>
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
The wages paid for that period.

I am stuck on the portion of the problem regarding the producing the output of test file 1:
I entered the following code:
# Get the file name from user
name = input("Enter the file name: ")
# open file in read mode
readFile = open(name, "r")
#Get the file contents through
#readlines method
fileConetent = readFile.readlines()
#Display statement
print("\nName\t\t\tHours\t\tTotalPay");
#Iterate the loop
for eachLine in fileConetent:
#split each line with empty space…

- in C#: Given a text file, write a program (console application) that counts the number of words that end with the letter "t" or "e" (not case sensitive). We’ll say that a "t" or "e" is at the end of a word if there is not an alphabetic letter immediately following it. The program should output the resulting count.arrow_forwardUsing C programming language. Write a program that reads a text file, and calculates the frequency distribution of individual letters in the file. Upper and lower case letters are considered the same. Numbers and punctuation are ignored. The frequency value should be the percentage that particular letter occurs in relation to all letters. Thus, the output will have two columns, each row will show the letter, and it's frequency (neatly formatted). Your program should prompt for the file name, and handle the case where the file isn't found. Use at least one user defined function (even if it's trivial) that's defined in a separate file, and use a header file that contains the declaration.arrow_forwardIn Python Define a function writeScores with two parameters. The first should be the name of a file, and the second should be a list of integer scores. The set of scores should be appended to the given file, one score per line.arrow_forward

For example 47, 911 are 2 such numbers, since the sum of the digits is > 9. After finding a number, you must immediately write it to the output file. Open the file, write the number you just found, and close the file. Measure how much elapsed time it takes to do this processing. Yes, it is inefficient, but we are trying to force some I/O usage, which will cause interrupts. When this process is completed, next have the program fork and create 10 separate processes. Each process would find search a range of 1 to 100,000 for these prime and sum 11 numbers. One process searches 1 to 10000, another 10001 to 20000 etc. Each process performs the exact same tasks , in the same way, as the first part of the problem, but write the output to 10 separate files, one for each process.
