Question
Create a function called file_reader() with the following parameters/arguments:
a. file_to_read
●くろまる String datatype
●くろまる Should contain the name of the file that you wish to write to
b. num_lines
●くろまる Integer datatype
●くろまる Should contain the number of lines that you would like to read from the
file
down below is what I have, im just not too sure how to indicate the 3 lines i would like read from the file:
function file_reader(string $file_to_read, int num_lines) {
$file_to_read = fopen($file_to_read, "r") or die ("unable to read file");
for ($i = 0; $i <$num_lines){

- Write a function named repeat_words that takes two string parameters: 1. in_file: the name of an input file that exists before repeat_words is called 2. out_file: the name of an output file that repeat_words creates Assume that the input file is in the current working directory and write the output file to that directory. For each line of the input file, the function repeat_words should write to the output file all of the words that appear more than once on that line. Each word should be lower cased and stripped of leading and trailing punctuation. Each repeated word on a line should be written to the corresponding line of the output file only once, regardless of the number of times the word is repeated. For example, if the following is the content of the file catInTheHat.txt: Too wet to go out and too cold to play ball. So we sat in the house. We did nothing at all. So all we could do was to Sit! Sit! Sit! Sit! The following function call: inF = 'catInTheHat.txt' outF =...arrow_forwardCreate a structure called applianceTvpe with the following members. Use the proper variable TYPES for the members: name; SUpplierlD: modelNo: cost; Create an array variable of type applianceType that can hold 50 components. Write the code segment to read from a file into the structure array. Declare an input file stream identifier for this purpose. Open the file and read until end of file. Keep a count of how many rows actually read. The data file contains the following data: RefrigeratorABC 80 4657 521.62 ToasterOven 100 3245 245.96 MicroWave 95 7878 345.67 Using a looping construct, output to the console (cout) the data read into the structure array. Make sure you do not go outside the bounds of the array or beyond the number of rows actually read. You do not need to write any #include statements, using statements and you do not have to write code to open the file. Assume the file is open. You do need to declare variables needed for the program segment.arrow_forwardUser Input Program and Analysis (Last answer to this question was incorrect.) Demonstrate an understanding of C++ programming concepts by completing the following: Program: Create a C++ program that will obtain input from a user and store it into the provided CSC450_CT5_mod5.txt Download CSC450_CT5_mod5.txtfile. Your program should append it to the provided text file, without deleting the existing data: Store the provided data in the CSC450_CT5_mod5.txt file. Create a reversal method that will reverse all of the characters in the CSC450_CT5_mod5.txt file and store the result in a CSC450-mod5-reverse.txt file. Program Analysis: Given your program implementation, discuss and identify the possible security vulnerabilities that may exist. If present, discuss solutions to minimize the vulnerabilities. Discuss and identify possible problems that can result in errors for string manipulation of data. Your analysis should be 1-2 pages in length.

The file contains Item ID, Description and list price stored on a separate line in the file. The program should display the contents of each record and then calculate and display the average list price. it is important that this is done in Thonny for python warrow_forwardWrite a program that uses a structure to store the following information on a company division: Division name (such as East, West, North, or South) Quarter (1, 2, 3, or 4)Quarterly salesThe user should be asked for the four quarters’ sales figures for the East, West, North, and South divisions. The information for each quarter for each division should be written to a file.arrow_forward
- 8-15. Printing Models: Put the functions for the example printing_models.py in a separate file called printing_functions.py. Write an import statement at the top of printing_models.py, and modify the file to use the imported functions.arrow_forwardThis part of the quiz will contain 4 parts. A function called grade, a function called pgrade, a prototype file called grade.h and a main function. In this part you will create the main function which will do the following: main This main function will use the functions grade and pgrade to produce the grades for the following students and display the appropriate grade with the appropriate message. The semester grade will be based on the fact that the quiz average is 25% of the grade, the final is 20% of the grade, assignments is 20% of the grade and programs are 35% of the grade. The student grades are as follows: Student Name Assignments Programs Quiz Ave Final Tom 63 Francis Maria Jan 75 90 95 85 sample of output Harry Grade B Good 85 75 95 90 93 92 71 69 87 91 73 Aarrow_forward1. Write a program named program61.py This program will have three functions, the main() create() and retrieve(). main() will call: create() and main() then calls retrieve() create() will prompt the user to enter any number of course name | grade values. The course name ,AND calculated class GPA ( not the class grade ) are the written one value per line to a file named grades.txt ( review example of grades.txt below! ). Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main(). See Simple GPA Tip below. retrieve() will open and read grades.txt. The function then will print the course names and Class GPA as shown below. The average of all class GPA values should be calculated and displayed to two decimal places and then return variable used for the GPA average to the main() .

- Open the project or solution named mpg in this folder: ex_starts\ch07_ex1_mpg Review the code and run the program to refresh your memory on how it works. Notice that, unlike the program in this chapter, this program lets the user perform more than one calculation, it stores the values the user enters in a text file, and it displays the total miles, total gallons, and average miles per gallon when the program starts and after each entry. Add a function that calculates the miles per gallon Define a function named calculate_mpg() before the main() function that calculates the miles per gallon. This function should accept two double values for the miles and gallons, round the result to two decimal places, and return the result as a double type. Modify the code in the main() function so it uses the calculate_mpg() function. Note that the miles per gallon is calculated in three different places. Move the definition for the calculate_mpg() function after the main() function.
