Chapter 7, Problem 7.11HW
This program header in Figure 7.14 indicates that the data segment occupies 0x230 bytes in memory. However only the first 0x228 bytes of these come from the sections of the executable file. What causes this discrepancy?
Figure 7.14 Program header table for the example executable prog. off: offset in Object file; vaddr/paddr: memory address; align: alignment requirement; filesz: segment size in object file; mersz: segment size in memory; flags: run-time permissions.

In python, rite 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... ...
Test this function in a new program.
In an executable object file that is in executable and linkable format (ELF), which section defines the addresses of the stack and the heap?
A. The data section
B. The .text section
C. These addresses are not defined in the executable object file. Instead, they are assigned by the operating system when the program is loaded in to me
D. These addresses are not defined in the executable object file. Instead, they are assigned by the user when the program is running in memory.

- Contiguous Memory Allocation Algorithms The program will read size of free memory partitions and size of processes from a text file and then will try to allocate a memory partition for each process using the first-fit, best-fit and worst-fit allocation algorithms. The implementation completed in Python programming language. The first line of the input file should contain the size of free memory partitions (in order) while the second line contains the size of processes (in order). Sample input file is shown below: 300,600,350,200,750,125 115,500,358,200,375 The program should read the name input file as command line input and produce a text file named “output.txt” with the following example output: First-Fit Memory Allocation ----------------------------------------------------------------------------------------------- start => 300 600 350 200 750 125 115 => 115* 185 600 350 200 750 125 500 => 115* 185 500* 100 350 200 750 125 358…arrow_forwardWrite a C program that performs the following tasks 1. The program should create three child processes. 2. Each child process should display its PID and the parent PID 3. The first child should display all the numbers from 1 to 100. 4. The second child should display all the content of the source file on the screen. 5. The third child should take two 2x2 arrays as an input and display their sum. 6. The main program should display the message "All child processes have completed" and then exit. 7 Ensure that the all the chiled processes complete their execution before the main program quits.arrow_forwardInstructions Write a C/C++ program that calculates the least squares line for two sets of values. The program consists of several functions which are described below. int ReadFile (int *, int *); Write a function that reads the contents of a text file (Data1.txt) into two separate integer arrays. The function receives two integer pointers to arrays as parameters. The contents of the text file that is attached is structured as follows: Each line in the file contains two values that are separated by a comma. The values on the left of the comma, are stored in one array and the values on the right side is stored in the other array. The number of lines that are read from the file and stored in the arrays are returned to the calling statement. Tip: a single fscanf can read into multiple variables. Ex. the statement fscanf(fp, "%s %s\n", name,surname) will read the line John Doe and save the name and surname separately. (Note the space between %s and %s indicates that there is a space in the…arrow_forward
- object of type streambuf. This object may represent a memory block that acts as an intermediary When we operate with file streams, these are associated to an internal between the stream and the physical file. For example, with an ofstream, each time the member function put (which writes a single character) is called, the character may be inserted in this intermediate buffer instead of being written directly to the physical file with which the stream is associated.

- 2. [summary_report.py] Timesheet data is easy to represent in a file, where it can be used to generate a report and help the worker get paid!

NMG789, GCTACTCGATGCTA.... .... The file can contain any number of rows. Write a program that reads in this file (you can create one to test your code with, use TextEdit or Notepad) and creates a dictionary, where the keys are the accession numbers and the values are the sequences. Print out to the screen the dictionary pairs that you created.arrow_forward
- Computer Science Write a C/C++ program, call it findExt, to find all files in a directory hierarchy, whose extensions are in the extension list provided as arguments to the program. Your program should print the whole pathnames of the found files. Synopsis: findExt <extension-list> [-t target-directory] When target-directory is missing, the working directory (./) will be the target directory Some sample runs: $ findExt txt pdf That is, find all files whose extensions are either txt or pdf in the directory hierarchy ./ $ findExt jpg -t $HOME //target directory is home directory That is, find all files whose extensions is jpg in the directory hierarchy $HOME Requirement: - You must use the system call nftw() that allows you to walk across a file tree. This system call will do all the recursive walk and each time it visits a file or a directory, it will call your own function (a function that you pass as a parameter).arrow_forwardThe 2 pictures are the beginning of the lab.
