Write a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet... File name: file_path2 Lorem ipsum dolor sit amet... ... # Put your code here import os   #module used to interact with operating system

In C++, Write a program that will inputstudent’s information (i.e. name, id, cgpa) who have enrolled forCSE-207 course in Spring 2022. You have to declare a pointer variable to inputthe information and dynamically allocate memory for storing information of eachstudents. You have to implement the following operation.i)                   Create a list with the given studentsinformationii)                  Delete a student of a given idiii)                Print the student having highest CGPAiv)                Sort and print the student id and namedescending order based on the CGPA.

Write a c program for a simple student record.Each record should contain the following information:● Surname – a string (surname of the student)● Sex – a character (M for male, F for female)● Year – an integer (year part of student number)● Snum – an integer (last five digits of the student number)● Department – a string (department the student is a part of)Your program should be able to allow the user to:● Add records● Display all records● Display all records filtered by sex/ year/ department● Display record(s) linked to a given snum (last five digits of a student number)Note: student number should be displayed following the format year - snum

Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…

Computer Science A system call in an operating system is typically a function call that traps to the kernel. However, there are also library calls that are functions that do not directly trap into the kernel, but may invoke system calls that do. In MINIX, there is a corresponding library call read that always invokes the system call. In UNIX, there are also several other library calls---getc, fgetc, getchar, for example---that also input data. Describe the difference between the MINIX read library call and these functions. How do you think these functions (getc, fgetc, getchar) perform data input? Do they always need to ultimately trap to the kernel? Why or why not?

Write a C/C++ program that: Writes a function, readFile(), that reads the content of the provided text file “stnumbers.txt” and stores it in an array of Student structs. The function receives as parameter an array of type Student structs. The number of lines that was read from the text file must be returned to the calling statement. If the file cannot be read, an error message should be displayed. stnumbers.txt textfile is given below Peterson20570856Johnson12345678Suku87654321Westley12345678Venter87654321Mokoena79012400Makubela29813360Botha30489059Bradley30350069

Add file i/o to your program Implement a function writeEmpToFile that takes two arguments: a struct Employee pointer and a FILE *. It should write each field in order as an appropriate type. Note that you will probably want to write a length of the name before you write the characters of the name. By doing this, when you write the load function below, you can read the length of the string and use it to malloc a buffer of the proper size to hold the name. Because of the embedded name pointer, you CAN NOT write the Employee struct as a single struct. You will need to write it out field by field. You will want to write this as a binary file, not as a text file. Implement a SAVE command in your main loop that will save all the employees out to a file. The SAVE command should ask for a file name, similar to the way your FIND command asked for a name. Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should…
