Language: C++
Design and write an object oriented program for the computation of the volume of boxes (having
a height, a width and a depth as double values). Your solution should have methods for setting
and getting the height, the width and the depth of a box as well as constructors (a default con-
structor and one which sets the data members), a copy constructor and a destructor.
files testbox.cpp, Box. cpp and Box.h.
The program testing your code (testbox.cpp) should do the following:
Name
your
a) Enter from the keyboard the a value for n, the number of boxes that will be entered.
b) Dynamically create an array of 2*n boxes.
c) Enter from the keyboard the height, width and depth of each box one after the other for the
first n boxes and the add their copies on the remainder n positions (in the same order). Use
the copy constructor for doing this.
d) Loop across all boxes, calculate and print on the screen the volume of each box.
You can assume that the input will be valid.

Half solve questions:
Mutual Exclusion:
Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex.
while (true)
{
semaphore sem = S;
while (S <= 0) do no operation
{
S = S-1;
wait (S);
}
/*critical section*/
while (S > 0)
{
S = S+1;
signal (S);
}
/*remainder section*/

When using a C++ inclusion guard on a library interface file, why is it essential that the
symbol or name used in the guard not be identical to any other uses of the symbol or name
in the guard? Assuming that the symbol does not need to be unique and then showing what
occurs when two libraries that are to be #included in the same application sharing the same
symbol is an effective use of the proof by contradiction technique in this circumstance. Here,
we have an actual application.

- Is there a special reason why the symbol or name used in the C++ inclusion guard on a library interface file has to be special? A helpful tactic in this situation is to use proof by contradiction: assume that the symbol doesn't need to be unique, and then show what happens when two libraries that are both #included in the same application use the same symbol.arrow_forwardWrite a C++ program that defines a class with a data member to holds a “serial number” for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you’ll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on.arrow_forwardProvide c++ code for main.cpp, dynamicarray.h and dynamicarray.cpp Step 1a: Preparation The suite of Part 1 tests has been moved to its own function. The code in main() is focused on testing the new operators you'll write in this part. main() relies on a change you're going to make to the DynamicArray::print() member function (coming up in Step 1b). Instead of directly using cout, this member function is now going to print to a stringstream. This allows my test code to examine the output and check it automatically. 3 representative lines of the new main program work: // Use stringstream to capture your print function's output.stringstream testoutput;// Use the same testoutput variable over and over, so we reset it to the empty string between tests using its str() member function.testoutput.str(""); // Reset test output string// Call the print function on your array, and it prints to testoutput instead of cout.a.print(testoutput);// Use the RunIndividualTest function also included in…arrow_forward
- 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:…arrow_forwardProgramming Assignment Containers are used to store objects of the same type and provide operations with which these objects can be managed. These operations include object insertion, deletion, and retrieval. Memory is allocated for containers dynamically at runtime. Containers thus provide a safe and easy way to manage collections of objects. The C++ standard library provides various class templates for container management in the Containers Library. These classes can be categorized as follows: Sequential containers, where the objects are arranged sequentially and access to an object can either be direct or sequential. Associative containers, where the objects are generally organized and managed in a tree structure and can be referenced using keys. Sequential Containers Sequential containers are distinguished by the operations defined for them, which are either generic or restricted. Restricted operations, such as appending at the end of a container, have constant…arrow_forwardIn a C++ program, create a Student class, where attributes associated with each student are name, registration number, father name, degree and department. All attributes should not be accessed directly. One can view the details of all students. Note student attributes can not be changed by anymeans after initialization. (Hint use constant objects)arrow_forward
- Why is it essential that the symbol or name used in the C++ inclusion guard on a library interface file be distinct from all other instances of that symbol or name? Proof by contradiction is a useful strategy to employ in this situation because it allows one to presuppose that the symbol does not need to be unique and then demonstrate what happens when two libraries that are to be #included in the same application share the same symbol. In this case, the application.arrow_forwardShow what is produced by the following C++ code. Assume the node is in the usual info-link form with the info of the type int. (first, temp, and p are pointers of type nodeType.) first = new nodeType;first->info = 78;p = new nodeType;p->info = 26;first->link = p;p->link = nullptr;temp = new nodeType;temp->info = 39;temp->link = first;p = first;first = temp;temp = p->link;cout << first->info << " " << temp->info << " "<< p->info << endl;arrow_forwardExplain the significance of the "implements" keyword when working with interfaces.arrow_forward
- Why must the symbol or name used in the C++ inclusion guard on a library interface file be distinct? Assume that the symbol does not need to be unique in this situation and show what happens when two libraries that are going to be #included in the same application share the same symbol.arrow_forwardIn C programming: Write a function inputCourse() which receives a course pointer and allows the user to input its information taking the size of each field into account. Test the function, but don’t include the testing code in your homework.arrow_forwardWhy does the C++ inclusion guard on a library interface file need a unique symbol or name? Assume that the symbol does not need to be unique and then show what happens when two libraries that are to be #included in the same application both use the same symbol.
