How many parameters are there in a unary operator implemented as a friend?
a. 0
b. 1
c. 2
d. as many as you need

Answers

Answer 1

There are two parameters in a unary operator implemented as a friend. The correct answer is option C.

In C++, a unary operator is an operator that operates on a single operand. When a unary operator is implemented as a friend function, it is defined outside the class but has access to the private members of the class. As a friend function, it takes two parameters: one for the operand on which the operation is performed and another parameter for the object or type that the operator is implemented for.

The first parameter represents the operand on which the operator is applied, and the second parameter represents the object or type that the operator is defined for. These two parameters are required for the friend function to perform the desired operation on the operand.

Option C is the correct answer.

connection speed is technically a measure of capacity: T/F

Answers

The statement "connection speed is technically a measure of capacity" is;

False.

Connection speed and capacity are not the same thing.

Connection speed, also known as bandwidth, is a measure of how quickly data can be transferred over a network connection. It is typically measured in bits per second (bps) or bytes per second (Bps). It is a measure of the rate of data transfer, and it is typically used to measure the speed of internet connections.

Capacity, on the other hand, is a measure of how much data can be stored or transmitted over a network connection. It is typically measured in bytes (B) or bits (b). It is a measure of the amount of data that can be transferred over a network connection, and it is typically used to measure the storage capacity of a hard drive or the number of users that can be supported on a network.

Therefore, connection speed is not a measure of capacity. The two are different from each other. Connection speed it is a measure of the rate at which data can be transferred over a network connection.

The term "memory" is most frequently used to describe the main storage on such a computer, including such RAM. Information is also processed in memory. Users can access data that's also temporarily saved thanks to it.

What are forms of memory?

Memory is the capacity to retain and recall knowledge when necessary. Cognitive function, short-term memory, long-term memory, as well as sensory memory are the four main categories of memory. Long-term memory is also divided into implicit (unconscious) and explicit categories (conscious).
