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'
Assume you have a folders of (images and videos) in your computer which contain some random mix numerical values. Your task is to separate images (e.g odd values) and videos (e.g Even values). So that all the images and videos are stored in separate folders (lists). While separating make sure that any of the folder (lists) should not contain any duplicate file or duplicate value. In this task images and videos odd & even numbers and folder means a single list of mix value. e.g: linkedlists (odd, even). Design a method for above task which will create two separate linked lists and write main method to test your program. FOLDER (VIDEO AND IMAGES:ODD AND EVEN VALUES) LIST 0: [2, 44 , 24 , 82 , 33 , 44 , 55 , 11 , 2 , 44 , 55]: EVEN VALUES_LIST 1: [2, 44 , 24 , 82]: A=2, B=44, C=24, D=82 ODD VALUES:_LIST 2: [33 , 44 , 55 , 11]: A=33, B=45, C=55, D=11
In this assignment, you will implement the shell “engine” as the “group” component, where all members are responsible for the following functionality: • A Command-Line Interpreter, or Shell Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. 1. Interactive Mode In interactive mode, you will display a prompt (any string of your choosing) and the user of the shell will type in a command at the prompt.
Challenge 3: Encryption.java and Decryption.java Write an Encryption class that encrypts the contents of a binary file. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded content out to a second file. The second file will be a version of the first file, but written in a secret code. Use a simple encryption technique, such as reading one character at a time, and add 10 to the character code of each character before it is written to the second file. Come up with your own encryption method. Also write a Decryption class that reads the file produced by the Encryption program. The decryption file will use the method that you used and restore the data to its original state, and write it to a new file.

2 CVS uses a simple text-based rule to identify overlaps during a merge: There is an overlap if the same line was changed in both versions that are being merged. If no such line exists, then CVS decides there is no conflict and the versions are merged automatically. For example, assume a file contains a class with three methods, a(). b(), and c(). Two developers work independently on the file. If they both modify the same lines of code, say the first line of method a(), then CVS decides there is a conflict. Explain why this approach will fail to detect certain types of conflict. Provide an example in your answer.
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,…
