In database access control area, which of following statement is the best to explain Authentication- verifying whether a user is the claimed user.

To the server or client, the user or computer must authenticate their identity. A user name and password are typically required for server authentication. Card-based authentication, retinal scanning, voice recognition, and fingerprint authentication are additional options.

Three categories of authentication factors exist: A token, like a bank card, is something you have; a password or personal identification number (PIN) is something you know; and biometrics, like voice and fingerprint recognition, are something you are.

To create one function to read the ids from the file employee.dat and tally how many belong to reach group and the function will need a temporary id variable to read into and evaluate, check the code given below.

A variable is a named piece of data that has a value. Even if the value changes, the name doesn't. Variables are a common feature of programming languages, and they can take many different forms, depending on the script or software programmer.

Some variables are mutable, which means that their values can be altered. Other variables, known as immutable ones, cannot have their values added, changed, or removed after they have been assigned.

When a variable's value must conform to a specific data type, it is said to be typed.

Enthalpy Changes the overall energy change in the substance portrayed in the graph at  48°C.

Mass (m) = 0.3 Kg

Initial temperature (T1) = 20°C

Heat (Q) added = 35 KJ

Specific heat capacity (C) = 4.18 KJ/Kg°C

Final temperature (T2)

The final temperature of water can be obtained as follow:

Q = MC(T2 – T1)

35 = 0.3 x 4.18 (T2 – 20)

35 = 1.254 (T2 – 20)

Clear the bracket

35 = 1.254T2 – 25.08

Collect like terms

1254T2 = 35 + 25.08

1.254T2 = 60.08

Divide both side by the coefficient of T2 i.e 1.254

T2 = 60.08/1.254

T2 = 47.9 ≈ 48°C

Average number of bits required to encode a character in Huffman code for the given weights and given frequencies is = 2 x 0.20 + 3 x 0.10 + 3 x 0.15 + 2 x 0.25 + 2 x 0.3 = 2.25

What is Huffman code?

A lossless data compression algorithm is huffman coding. Input characters are given variable-length codes, the lengths of which are determined by the frequency of the matching characters.

The character used the most often is given the smallest code, and the character used the least often is given the largest code.

The variable-length codes (bit sequences) assigned to input characters are Prefix Codes, which indicates that no other character will have a code that is the prefix of the code assigned to that character.

This is how Huffman Coding ensures that the produced bitstream cannot contain any ambiguities during decoding.

The concept of prefix code, which states that a code associated with a character should not be included in the prefix of any other code, is used by Huffman Coding to avoid any ambiguity in the decoding process.

Answer:The Polynom3 class represents polynomials of the third degree from one given variable with an array of coefficients. It has the following methods:

Polynom3(const Polynom3& other): This is the copy constructor, which creates a new Polynom3 object as a copy of another Polynom3 object.

Polynom3& operator=(const Polynom3& other): This is the copy assignment operator, which allows you to assign one Polynom3 object to another, replacing the original object with a copy of the other object.

Polynom3 operator+(const Polynom3& other) const: This is the addition operator, which adds two Polynom3 objects and returns a new Polynom3 object representing the sum of the two polynomials.

Polynom3 operator-(const Polynom3& other) const: This is the subtraction operator, which subtracts one Polynom3 object from another and returns a new Polynom3 object representing the difference between the two polynomials.

Polynom3 operator*(const Polynom3& other) const: This is the multiplication operator, which multiplies two Polynom3 objects and returns a new Polynom3 object representing the product of the two polynomials.

friend std::ostream& operator<<(std::ostream& out, const Polynom3& polynom): This is the output operator, which allows you to print a Polynom3 object to an output stream, such as std::cout.

Here is an example of how you could use these methods:

Polynom3 p1({1, 2, 3});  // Creates a polynomial p1 = 1x^2 + 2x + 3

Polynom3 p2({4, 5, 6});  // Creates a polynomial p2 = 4x^2 + 5x + 6

Polynom3 p3 = p1 + p2;   // Creates a new polynomial p3 = 5x^2 + 7x + 9

Polynom3 p4 = p1 - p2;   // Creates a new polynomial p4 = -3x^2 - 3x - 3

Polynom3 p5 = p1 * p2;   // Creates a new polynomial p5 = 4x^4 + 13x^3 + 22x^2 + 17x + 18

std::cout << p3 << std::endl;  // Outputs "5x^2 + 7x + 9" to the console

Explanation:

The third-degree polynomials from a given variable with an array of coefficients are represented by the Polynom3 class.

Many people believe that C++, an object-oriented programming (OOP) language, is the finest language for developing complex applications.

The copy assignment operator, Polynom3& operator=(const Polynom3& other), enables you to assign one Polynom3 object to another, replacing the original object with a duplicate of the other object.

The addition operator, Polynom3 operator+(const Polynom3& other), returns a new Polynom3 object that represents the sum of the two polynomials after adding two Polynom3 objects.

This Polynom3 operator subtracts one Polynom3 object from another using the formula (const Polynom3& other).

The Polynom3 operator*(const Polynom3& other) const multiplies two Polynom3 objects and creates a new Polynom3 object that represents the result of the multiplication.

Thus, this way, a description of the Polynom3 class of polynomials of the 3rd degree from one given variable can be done.
