You are to use the started code provided with QUEUE Container Adapter methods and provide the implementation of a requested functionality outlined below. The program has to be in c++, and have to use the already started code below. Please make sure the code is able to add order, next order, previous order, delete order, order size, view order list, view current order, and exit program. Scenario: A local restaurant has hired you to develop an application that will manage customer orders. Each order will be put in the queue and will be called on a first come first served bases. Develop the menu driven application with the following menu items: Add order Next order Previous order Delete order Order Size View order list View current order Order management will be resolved by utilization of an STL-queue container’s functionalities and use of the following Queue container adapter functions: enQueue: Adds the order in the queue DeQueue: Deletes the order from the queue Peek:…

write in c++Write a program that would allow the user to interact with a part of the IMDB movie database. Each movie has a unique ID, name, release date, and user rating. You're given a file containing this information (see movies.txt in "Additional files" section). The first 4 rows of this file correspond to the first movie, then after an empty line 4 rows contain information about the second movie and so forth. Format of these fields: ID is an integer Name is a string that can contain spaces Release date is a string in yyyy/mm/dd format Rating is a fractional number The number of movies is not provided and does not need to be computed. But the file can't contain more than 100 movies. Then, it should offer the user a menu with the following options: Display movies sorted by id Display movies sorted by release date, then rating Lookup a release date given a name Lookup a movie by id Quit the Program The program should perform the selected operation and then re-display the menu.

Exercise 7: We have two Series defined as follows: available: import pandas as pd s1 = pd. Series ([11, 25, 55, 10], index = ['g', 'r', 'p', 'a']) s2 = pd. Series ([20, 30, 40]) We create a DataFrame by: df = pd.DataFrame({"coll": 1, "col2": s2}) a) What is len(df.index)? Why? b) Why are all the NaN values created in df?
Compliant/Noncompliant Solutions The following code segment was provided in Secure Coding Guidelines for Java SE: void readData() throws IOException{ BufferedReader br = new BufferedReader(new InputStreamReader( new FileInputStream("file"))); // Read from the file String data = br.readLine();} The code is presented as a noncompliant coding example. For this assignment, identify two compliant solutions that can be utilized to ensure the protection of sensitive data. Provide a detailed explanation of factors, which influence noncompliant code and specifically how your solutions are now compliant. Your explanation should be 2-3 pages in length. Submit the following components: Word document with appropriate program analysis for your compliant solutions and source code in the Word file. Submit your .java source code file(s). If more than 1 file, submit a zip file.
In this project you are to design a process queue that is responsible for handling the process requests coming from different users. You have to take into consideration that users have different levels of privileges and priorities. Each user has an identification number and a password, in addition to process priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every process request received, the program should check the privileges of that request and whether it can be moved forward in the queue to be served by the operating system prior to serving the other requests. Using the programming language of your choice (preferably C+), write the process queue that would handle the user request. The program must allow for requests coming from different users or from one user.

Which of the following is true? a) Union may be compared using the == operator. b) The address operator (&) can not be used to take the address of a union. c) Unions may only contain two data types. d) Only one union members and thus one data type can be referenced at a time.
Consider the following code snippet: waitpid(-1, &status, 0); Which of the following correctly describes the purpose of this code snippet? it is equivalent to wait(&status); it causes the parent process to wait for the child process that terminates first and fetch that child's termination status it causes the parent process to wait for the child process whose pid is -1 and fetch that child's termination status The first two choices are both correct None of the above choices are correct Which of the following statements about wait(2) and waitpid(2) are true? The waitpid(2) function can block the caller until a child process terminates, whereas wait(2) has an option that prevents it from blocking. The wait(2) function doesn't wait for the child that terminates first; it has a number of options that control which process it waits for. If a child has already terminated and is a zombie, wait(2) returns immediately with that child's status. Otherwise, it blocks the caller until a child…
