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.

The semantics of a call to a “simple” subprogram requires the following actions: A. Save the execution status of the current program unit. B. Compute and pass the parameters. C. Pass the return address to the called. D. Transfer control to the called. E. All of the above

A fast food restaurant is planning to develop a system to process customer’s orders. The system receives food orders from the users, and stores and processes according to the order in which the users placed the orders. The system can remove an order from the list of orders once the order is complete. The system can also display the order which is currently being processed by the employees. The system displays the list of orders as well. The system displays all these options as a menu of choices to a user and performs the operations according to the user’s selection. (Please see the test runs on the next page). Write a program in C/C++ to develop a simple order processing system for the fast-food restaurant. In your program, you must use queue to store and process customer’s orders. Your program must use a linked list to perform the queue operations. Your output format should be as shown in the test runs (see the next page). Your program must contain the following user-defined…

Help write a C++ Program to do the following: This is to create a prototype for a Web browser. You’ll do this by transforming the file viewer created (SHOWN BELOW) into a browser for a web of files that are all located on a single computer. (This is in contrast to the real World Wide Web whose pages are located all over the world.) Details The files in this web of files are plain text files that may contain anchors that provide links to other files. More precisely, an anchor is a string of the form 1 where filename is the name of another file and text is a piece of text. For example, here’s a line of text that contains an anchor: More is available. To keep things simple, assume that every anchor is separated from adjacent text by white space and that the strings filename and text cannot contain white space. Your browser should work exactly like the file viewer, except for the following: 1. When an anchor is displayed, it should appear as [n] where n is a number that is unique to…

Demonstrate an understanding of basic C++ programming concepts by completing the following: Program: Create a simple C++ console application that will write a program that will take two string inputs from a user.  Your program should concatenate the two strings and then print the resulting output to the screen. Take the two string inputs from the user 3 times for varying string lengths. Program Analysis: Given your program implementation, discuss and identify the possible vulnerabilities that may exist. If present, discuss solutions to minimize the vulnerabilities. Then discuss and identify possible problems that can result in errors for string manipulation of data. Your program analysis should be 1-2 pages in length.

A valid email address consists of an email prefix and an email domain, both in acceptable formats. The prefix appears to the left of the @ symbol. The domain appears to the right of the @ symbol. For example, eng221t@mail.com, "eng2217" is the email prefix, and "mail.com" is the email domain Write a C++ program, which reads the email addresses from the file (input.txt) and find out whether it is a valid email address or not based on the following rules. 1. The email address must start with a letter (a-z or A-Z) (no numbers or symbols). 2. There must be an @ somewhere in the string that is located before the dot. 3. There must be text after the @ symbol but before the dot. 4. There must be a dot and text after the dot e.g.( ali@gmail.com). For each valid email address, the program should find its Prefix and Domain. You must have to use only one user defined function that has the following prototype. bool checkValid(string email); In this function definition you have to check whether the…
