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. Thecommand 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 andargv.

In this assignment, you will create a Java program to search recursively for files in a directory.• The program must take two command line parameters. First parameter is the folder to search for. Thesecond parameter is the filename to look for, which may only be a partial name.• If incorrect number of parameters are given, your program should print an error message and show thecorrect format.• Your program must search recursively in the given directory for the files whose name contains the givenfilename. Once a match is found, your program should print the full path of the file, followed by a newline.• You can implement everything in the main class. You need define a recursive method such as:public static search(File sourceFolder, String filename)For each subfolder in sourceFolder, you recursively call the method to search.• A sample run of the program may look like this://The following command line example searches any file with “Assignment” in its name%java FuAssign7.FuAssignment7…

C++ PLEASE!! Working on a project that is about word count with MapReduce, need a file manager class to take care of reading all txt file from a directory with giving path. The file manager class need to open the directory with the giving path which the user will input, then open the path and open all the txt files in that directory and break the text into single line and pass it to another class to do mapping. Please help with the file manager class!! Thank you!!
Create a new file in c++. In this lab, you will add some functionality to the table ofmenu. Your boss (me) has decided that letters should be used for menu items instead of digits (because there are more alpha characters than numeric ones, so more additional menu items could be added in the future). We all know that programmers are lazy, but so are most users! So, the user should be able to enter either uppercase (A) or lowercase (a) for their menu selection. Also, it is important to let the user know if they entered an invalid choice. Write a program that displays the following menu and prompts the user for a selection. Once the selection has been made, display the selection back to the user. Then, ask the user for two numbers and perform the selected operation (+, -, *, /). Display the results back to the user (e.g. 2 + 3 = 5). When dividing, display an error message if the second number is 0. A) Add two numbers B) Subtract two numbers C) Multiply two numbers D) Divide two…
This C++ menu-driven program on LIBRARY MANAGEMENT SYSTEM has book and student class with data members like a book no, book name, author name. Books records are stored in a binary file. A student can issue a book and deposit it within 15 days. The student is allowed to issue only one book. Student Records are stored in the binary file. The administrator can add, modify or delete records.In this project, do not use graphics to keep the program simple.
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,…
please 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…
sing good OOP, write a C++ program that will read an input file to manage a list of students waiting to register for a ourse using a linked list. The input file name is WaitList.txt and is located in the current directory of the project. The file layout is as follows: action student name Actions are defined as follows: 1 - add student name to the end of the linked list2 - add student name to the beginning of the linked list3 - delete the student at the beginning of the linked list4 - delete the student at the end of the linked list Actions #1 and #2 require student names. Actions #3 and #4 do not. For example, if the input file contents contained: 1 Sally Sue Student1 Peter Pupil1 Sam Scholar42 Terri Tutor1 Abby Achiever32 Bill Brain The program would display the wait list as follows: The Wait List: 1. Bill Brain2. Sally Sue Student3. Peter Pupil4. Abby Achiever End of List. Then the program will prompt the user if they wish to delete a student by name. If…
Write a script that opens a file containing a list of passwords and checks to see if the passwords are strong. 1. Save a list of five passwords in a text file. 2. Write a Python script that opens the text file and reads the passwords. 3. For each password, use regular expressions to check the password strength (I recommend creating a module to do this). For a password to be considered strong, it must satisfy the following requirements: + minimum length 8 characters + must contain one or more alphabetical characters [a-z] + must contain one or more Uppercase characters [A-Z] + must contain one or more numeric characters [0-9] + must contain one or more special characters [_$!]
Use the Bash shell for the completion of this project.Develop a shell scripting application that allows the user to perform some advanced mathematicaloperations. Task 2: Find the terms of any linear sequence given by the rule Term = a*n + b, where a and b are integers specified by the user and n is a positive integer and print them in order (for example if the user inputs a=3, b=-4, the first few terms that should be printed are -1, 2, 5, 8, 11…). The user also will specify how many terms the program should print. In addition, the program should print the sum of terms found and a count of how many odd terms were found.
In this assignment, you will create a Java program to read undergraduate and graduate students from an input file, sort them, and write them to an output file. This assignment is a follow up of assignment 5. Like assignment 5, your program will read from an input file and write to an output file. The input file name and the output file name are passed in as the first and second arguments at command line, respectively. Unlike assignment 5, the Student objects are sorted before they are written to the output file. • The program must implement a main class, three student classes (Student, UndergradStudent, GradStudent), and a Comparator class called StudentIDComparator. • The StudentIDComparator class must implement the java.util.Comparator interface, and override the compare() method. Since the Comparator interface is a generic interface, you must specify Student as the type parameter when defining the StudentIDComparator class, i.e., public class StudentIDComparator implements…
Write a C program that: takes an input file name from the command line; checks argc for correct invocation (otherwise, prints error and quits); opens that file if possible; prints a message confirming that the file has been opened successfully; and closes the file. For 3rd point program should print an error message in the event that the file cannot be opened successfully.
