The statement "VLOOKUP searches for a value in a row to return a corresponding piece of information" is True.

VLOOKUP is a Microsoft Excel function that searches for a value in the first column of a table and returns a corresponding value in the same row. VLOOKUP stands for "Vertical Lookup."This function searches for a value in the leftmost column of a table or an array, then returns a value in the same row from a column that you specify. For instance, suppose you have a table of employee information. You could use VLOOKUP to search for an employee's ID number and retrieve their name, address, or phone number.

The VLOOKUP function is an Excel function that searches for a value in the first column of a table, and if found, returns a corresponding value in the same row. The function takes four arguments, all of which are required. The first argument is the lookup value, the second is the table array, the third is the column index number, and the fourth is the optional range lookup argument.

The feature that distinguishes a LAN from a WAN is that (D) "a LAN connects computers in a single location".

A LAN (Local Area Network) is a computer network that connects devices in a small geographical area, such as a home, office, or building. In contrast, a WAN (Wide Area Network) is a network that covers a larger geographical area, such as a city, country, or even the whole world. The main difference between the two is the size of the area they cover and the number of devices they connect. LANs typically have higher bandwidth and faster data transfer rates, while WANs often have lower bandwidth and slower transfer rates due to the distance between devices. Both LANs and WANs can be used to share resources and data, but they are designed to meet different needs.

The most distinguishing feature of the use of a client-server processing model over an old mainframe configuration is the distribution of computing power.

A client-server processing model is a distributed application structure that partitions tasks or workload between service providers and service requesters, called clients. Each computer in the client-server model operates as either a client or a server. The server provides services to the clients, such as data sharing, data manipulation, and data storage.

The client requests services from the server, allowing for the distribution of processing responsibilities between the two entities. In this model, the server is responsible for storing data, while the client is responsible for data retrieval. A mainframe configuration is an older computing model that is centralized, where the mainframe performs all computing activities.

All users are linked to the mainframe, which stores all data and applications, as well as handles all processing responsibilities. Mainframes can handle a large amount of data and have a lot of processing power, but they are inflexible and can be difficult to scale. The distribution of computing power is the most distinguishing feature of the use of a client-server processing model over an old mainframe configuration.

With the exception of the assignment operator and the member selection operator, operators must be overloaded to be used on class objects.

The two operators in C++ that do not need to be overloaded are the assignment operator (=) and the member selection operator (.). These operators are not overloaded because they can only be used with fundamental types in C++. The remaining operators must be overloaded to be used with class objects, such as the multiplication operator (*), the addition operator (+), and the subtraction operator (-).

This means that when you use these operators with objects of your class, you must define the operation's behavior. A class can overload a member function that provides an operator definition, allowing it to be used with objects of that class. When using an operator on a class object, the definition of that operator for that class will be used.

When an operator is overloaded for a class, the overloaded operator can be used with objects of that class in the same way that other operators can be used with objects of built-in types.
