When a dynamic array with a class for a base type is declared, which constructor is called?

1 answer:

5 0

The default constructor is called for each element of the array. So if you declare an array with 100 elements (object instantiations), the constructor is executed 100 times!

lozanna [386]

Answer:

Internet Protocol and Transmission Control Protocol

Explanation:

Internet protocol, which is also known as IP and Transmission Control Protocol, which is also known as TCP are the two important protocols that enables the computers to communicate various information and data and allow it to pass between two networks. It allows computers to connect to each other. They are developed by Bob Kahn and Vint Cerf.

Suppose you wish to develop a matrix-multiplication algorithm that is asymptotically faster than Strassen’s algorithm. Your algo

Kazeer [188]

Answer:

The number of subproblems are given as $T(n)=a*T(n/8)+\theta(n^2)$ while the value of T(n) to be less than S(n) is for 342.

Explanation:

The number of subproblems are given as

$T(n)=a*T(n/8)+\theta(n^2)$

Asymptotic running time for Strassen’s algorithm is $S(n)=\theta(n^{log(7)})$

Now, when a increases, number of subproblems determines the asymptotic running time of the problem and case 1 of master theorem applies. So, in worst case, asymptotic running time of the algorithm will be

$T(n)=\theta(n^{logb(a)})=\theta(n^{log8(a)})=\theta(n^{log_{2}(a^{1/3})})$

Now, for T(n) to be smaller than S(n)

$n^{loga^{1/3}}$

So,

$log(a^{(1/3)})$

So,

a=342

Networks provide businesses with these benefits.

tekilochka [14]

Answer:

1. Easier collaboration.

2. Improved communications.

3. Increased productivity.

4. Reduced cost.

Explanation:

Computer network is a group of computers connected together using a common communication protocol for the purpose of transmitting data electronically and sharing resources such as internet, printers, scanner etc. The computer network is mainly divided into three, these include;

- Wide Area Network (WAN).

- Metropolitan Area Network (MAN).

- Local Area Network (LAN).

Also, a network is made up of nodes, which comprises of systems or devices that are connected to a network and are capable of sending, receiving or transferring data e.g switch, hub, computer, server, printer etc.

The benefits of the computer network are, it improves communication, convenient resources sharing, reduced operating costs, increase productivity, flexibility and efficiency for users.
