Step by step
Solved in 3 steps
- Write a menu driven C++ program in Linux that shows the following: 1. Zombie Technique, 2. Orphan Technique, 3. Wait ( ) System Call, 4. Fork ( ) System Call, 5. Exec ( ) System Call, (Note: Output must be shown on Linux Terminal ).With this type of parameter, we can omit the name and the cmdlet would still work. For example, the -Name parameter of the Get-Command cmdlet is this type of parameter, so Get-Command -Name Get-Help works the same as Get-Command Get-Help. Group of answer choices Optional Parameter Required Parameter Positional Parameter Default Parameterchoose 3 different Linux flavors - also called "distros" (distributions) - and research them. Write a summary paragraph about each one, for a total of 3 paragraphs. Include a references section at the end of your assignment with active links to all the sources you use. Notes: Don't use Ubuntu.
- PROGRAMMING LANGUAGE: C++ Please test the code first before uploading here in bartleby. The expected outcome for each of the test case is also given in the screenshot. Follow accordingly. Thanksplease write c++. thanks in advance. ATTENTION : Your project Name shall be like 200201543.dev and you must upload to OTUZEM together with related .cpp files and class interface file. Ostim Technique University Proffessor is teaching two courses, namely CENG103 and CENG104. For each course registration quota is maximum 25 students. At the end of the semester, both courses final grades are written in the same sequential access file, namely CE103-104.txt. The format of sequential file is given below. The program will read the CE103-104.txt file and for each course, the average of the final exam grades will be calculated, highest score and lowest score will be found. Your program will define related objects for each course. These operations will be performed by the related course objects' member functions. The class interface file and member functions implementations of the class will be located in separate files. Hint: Use the sample program files given in the class studies. Sample…Write the C or C++ program system2 that reads, when being executed, OS commands via the "command line parameter" C/C++ feature, and then executes them. The command line parameters must be legal Unix/Linux commands. Print the number of commands entered. To prepare, read about argc, argv, and envp. Focus is only argc and argv. A sample execution by fictitious user "mike" is: herb$ ./a.out pwd ls whoami argc 4 pwd argv[1] Executing command /Users/mikey 'pwd' = ls argv[2] Executing command 'ls' Applications Contacts Music Pictures familie herb Downloads testl Favorites Library Movies testl.c pix_low_2020 test2 test2.c Desktop Public Documents a.out test.c argv[3] = whoami Executing command mikey 'whoami'
- In Section 3.1 question 32 (textbook version 11), complete the table by filling in the value for each variable after each line is executed. Can you actually solve the question? step by step? Because I know the explanation already. I just don't know how to do it in Vistual Basic..Implement a simple version of the linux grep command in C++. grep - Looks through a file, line by line, trying to find a user-specified search term in the line. If a line has the word within it, the line is printed out, otherwise it is not. Use the system calls open(), getline(), close(). Requirements (examples run from. terminal) Your program grep is always passed a search term and zero or more files to grep through (thus, more than one is possible). It should go through each line and see if the search term is in it; if so, the line should be printed, and if not, the line should be skipped. [terminal]$ ./grep ! main.cpp main2.cppcout << "Hello, World!";cout << "Programming is great fun!"; The matching is case sensitive. Thus, if searching for world, lines with World will not match. Lines can be arbitrarily long (that is, you may see many many characters before you encounter a newline character, \n). grep should work as expected even with very long lines. For this,…The issue: Do you "sort of" know what method you're looking for's name? Because the procedures in the Windows API have incredibly inconsistent names, this is a common issue for programmers who work with Microsoft Windows. Not much better are UNIX programmers. The only issue is that UNIX prefers to omit letters from system call names (for instance, creat), which results in naming conversions that are inconsistent.
- 5. Discuss whether the following task is possible to implement. The argument and the discussion are important. Password cracker: A company that does not want to be named asks you to develop a password cracker for Windows. They provide you with access and ways to test passwords, but this test takes some time. They tell you that time and money are not relevant, just make it work. The positive side is that the passwords are never changed - they stay the same all the time. P.S.: This task has some tricky ethical implications, which are not relevant here. Just think whether this is possible or not.This type of parameters allows us to omit including the parameter name and simply provide the value and it would work just fine. One example is the -Name parameter in the Get-Command This is why the Get-Command Get-Help cmdlet works the same as the Get-Command -Name Get-Help cmdlet. Group of answer choices String Parameter SwitchParameter Required Parameter Positional ParameterYou should not make any changes to DPQueue.h. ■ You should not remove any functions from DPQueue.cpp, and you need to: ● Fill in the implementation of all the "stub" functions in the file (those with output statements containing the message "??? not implemented yet"), and ● Provide any additional documentation where appropriate. The file SuccessfulAutoTest.txt shows how the output for a test with complete success should look like. ► Referring to it should give you a purview of the number/kind of tests involved. #endifusing namespace std; namespace CS3358_FA2022_A7{ // CONSTRUCTORS AND DESTRUCTOR p_queue::p_queue(size_type initial_capacity) { cerr << "p_queue() not implemented yet" << endl; } p_queue::p_queue(const p_queue& src) { cerr << "p_queue(const p_queue&) not implemented yet" << endl; } p_queue::~p_queue() { cerr << "~p_queue() not implemented yet" <<…
