program. - please make it simple and DONT use Java
Create a program and reads a MAC address and determines whether it is syntactically correct or not. Assume the format of the MAC address is dd-dd-dd-dd-dd-dd where dd represents a 2-character hexadecimal number (each character is a digit or a letter between a and f). Use the `split function to access the values in the input MAC address.

- need help on this. Thanks in advance!arrow_forward-)Write a C++ program that presents a menu for the user. The menu should consist of the following: Create a linked list of 5 nodes containing names and phone numbers. Insert a new structure in the linked list. (between the 4 and the 5 node) Modify an existing structure in the linked list.(modify node 4) Delete an existing structure from the list (delete node 5) Exit from the program Note: based on the user’s selection the program should execute a function to satisfy the request. (Items: 3, 4, and 5,)arrow_forwardC++ In this project you will implement two small programs. One program will show an example of stack use and another program will show the use of a Queue 1. Use the STL to create your data structures 2. You should have the following features: a. Add a record b. Find a record c. Delete a record e. View all recordsarrow_forward
- With the help of a high-level language, write a program to execute the push operations in stack and in queue. Insert appropriate comments to explain the program to a novice indicating how the program executes.arrow_forwardC++ Can someone answer the following code below in C++: Please add to the project a print statement that says how long each version ran in milliseconds please! Version 1 of the process creation hierarchy uses linked lists to keep track of child processes as described in section "The process control block", subsection "The PCB data structure". For the purposes of performance evaluation, the PCBs are simplified as follows: All PCBs are implemented as an array of size n. Each process is referred to by the PCB index, 0 through n-1. Each PCB is a structure consisting of only the two fields: parent: a PCB index corresponding to the process's creator children: a pointer to a linked list, where each list element contains the PCB index of one child process The necessary functions are simplified as follows: create(p) represents the create function executed by process PCB[p]. The function creates a new child process PCB[q] of process PCB[p] by performing the following tasks: allocate a…arrow_forwardProblem D. Find URLsHTML is a language for representing documents designed to be displayed by a web browser. In many browsers, you can see the HTML source code by right-clicking somewhere on the page and clicking “View Page Source”. If you try this on a web page with links to other websites, you’ll notice that the URL of the link is usually formatted in the following way: href="https://some.website.com/subfolder/more_stuff.txt" Write a function find_url(html) that takes in a string of html text that contains exactly one external link URL formatted as above, and returns just the URL string (in the above example, that would be https://some.website.com/subfolder/more_stuff.txt). You can assume that the only place in the string where the substring href=" occurs is right before the URL, and that the next quotation mark after that point denotes the end of the URL. Hints: ● The .find method and string slicing will likely make this easier. ● Remember that in order to use a double quote…arrow_forward
- in PERL programming: Consider the list (784,785,754,1035,776,775). Please extract from the list the numbers that ends to 5. Please use one statement.arrow_forwardC++ Code Use the following list to sort it and create a single linked list: 6,13,7,11,9,2,15,5,3,4,10,14 Also make a list of the available memory. Print the list out with the links. Now delete 11 from the list, adding its location to the available memory list, then add 1 and 8 to the list. When you add the 1 you should use the location of the deleted 11 to add 1 there. Add 8 to the next available spot on the available memory list. When you print the list, print out the logical list using the links and also print out physical list without the links to see what the real list looks like.arrow_forwardCreate the following operations and include a menu-driven main program that will demonstrate your operations.
