To create an online shopping cart. You need to do the following:

Update the ItemToPurchase struct to include a new data member called itemDescription.

Create three new files: ShoppingCart.h, ShoppingCart.c, and main.c.

Build the ShoppingCart struct with the following data members: customerName, currentDate, cartItems (which can hold up to 10 items of any quantity), and cartSize.

Implement the AddItem, RemoveItem, ModifyItem, GetNumItemsInCart, GetCostOfCart, PrintTotal, and PrintDescriptions functions for the ShoppingCart struct.

In the main function, prompt the user for a customer's name and today's date, and create an object of type ShoppingCart.

Implement a menu of options to manipulate the shopping cart in the PrintMenu function in main.c.

Implement the ExecuteMenu function in main.c to perform the menu options according to the user's choice.

Implement the "Output shopping cart" menu option in ExecuteMenu.

Implement the "Output item's description" menu option in ExecuteMenu.

Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:

A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1

The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.

We can observe that the output of the logical statement is the same as the output of the OR gate.

Given the logical circuit, we are required to perform two actions on it. Firstly, convert the circuit into a logical statement. Secondly, create a truth table based on the circuit/statement. Let's understand how to do these actions one by one:Conversion of Circuit into Logical Statement.

The given circuit contains three components: NOT gate, AND gate and OR gate. Let's analyze the working of this circuit. The two input variables A and B are first passed through the NOT gate, which gives the opposite of the input signal.

Then the NOT gate output is passed through the AND gate along with the input variable B. The output of the AND gate is then passed through the OR gate along with the input variable A.We can create a logical statement based on this working as: (not A) and B or A. This can also be represented as A or (not A) and B. Either of these statements is correct and can be used to construct the truth table.

Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:

A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1

In the truth table, we have all possible combinations of input variables A and B and their corresponding outputs for each component of the circuit.

The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.

We can observe that the output of the logical statement is the same as the output of the OR gate.

Both pneumatic and hydraulic systems can be used to push heavy objects. However, the choice between these two systems depends on several factors, including the specific application, the load capacity, the required force, and the environment.

In general, if the application requires higher force and load capacity, a hydraulic system is typically preferred over a pneumatic system. Hydraulic systems use a liquid, such as oil, to transmit power and can generate higher forces than pneumatic systems, which use compressed air.

Additionally, hydraulic systems are typically more durable and can operate in harsh environments, such as high temperatures and corrosive conditions. They also offer more precise control and can be adjusted to provide a smooth and consistent force.

Explanation:

An operating system (OS) is a system software program that operates, manages, and controls the computer's hardware and software resources. The OS establishes a connection between the computer hardware, application programs, and the user.

Its primary function is to provide a user interface and an environment in which users can interact with their machines. The OS also manages the storage, memory, and processing power of the computer, and provides services like security and network connectivity.

Examples of popular operating systems are Windows, macOS, Linux, iOS, and Android. These OSs have different user interfaces and feature sets, but they all perform the same essential functions. The OS is a fundamental component of a computer system and is responsible for ensuring the computer hardware operates efficiently and correctly.

The OS performs several key tasks, including:

1. Memory management: Allocating memory to applications as they run, and releasing it when the application closes.
2. Processor management: Allocating processor time to different applications and processes.
3. Device management: Controlling input/output devices such as printers, scanners, and other peripherals.
4. Security: Protecting the computer from malware, viruses, and other threats.
5. User interface: Providing a graphical user interface that enables users to interact with their machine.

Cache memory is typically positioned between the CPU and the hard drive. A cache memory is used by a computer's central processing unit to reduce the average cost time or energy required to access data from the main memory.

Cache memory is a chip-based computer component that improves the efficiency with which data is retrieved from the computer's memory. It serves as a temporary storage area from which the computer's processor can easily retrieve data.

A cache is a hardware or software component that stores data in order to serve future requests for that data more quickly; the data stored in a cache may be the result of an earlier computation or a copy of data stored elsewhere.

When the requested data can be found in a cache, it is called a cache hit; when it cannot, it is called a cache miss. Cache hits are served by reading data from the cache, which is faster than recalculating a result or reading from a slower data store; as a result, the more requests that can be served from the cache, the faster the system performs.

Caches must be relatively small in order to be cost-effective and enable efficient data use. Nonetheless, caches have proven useful in a wide range of computing applications because typical computer applications access data with a high degree of locality of reference.
