Aleksandr [31]

Answer:

Explanation:

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.

double alpha[50];

for (int i=0;i<25;i++)

{

alpha[i]=i*i;

alpha[i+25]=(i+25)*3;

}

2. Output the array so that exactly ten elements per line are printed.

for (int i=0;i<50;i++)

{

cout<<i+1<<". "<<alpha[i]<<" ";

if (((i+1)%10)==0)

{

cout<<endl;

}

3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.

double alpha[50];

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

}

for (int i=0;i<50;i++)

{

cout<<i+1<<". "<<alpha[i]<<" ";

if (((i+1)%10)==0)

{

cout<<endl;

}

4. Write the code that computes and prints the average of elements of the array.

double alpha[50],temp=0;

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

temp+=alpha[i];

}

cout<<"Average :"<<(temp/50);

5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.

double alpha[50],temp=0;

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

if(alpha[i]==100)

{

temp++;

}

cout<<"Elements Exacctly 100 :"<<temp;

Please note: If you put each of above code to the place below comment it will run perfectly after compiling

#include <iostream>

using namespace std;

int main()

{

// If you put each of above code here it will run perfectly after compiling

return 0;

poizon [28]

Answer:

The Java code is given below with appropriate comments for explanation

Explanation:

// java code to contradict birth day paradox

import java.util.Random;

public class BirthDayParadox

{

public static void main(String[] args)

{

Random randNum = new Random();

int people = 5;

int[] birth_Day = new int[365+1];

// setting up birthsdays

for (int i = 0; i < birth_Day.length; i++)

birth_Day[i] = i + 1;

int iteration;

// varying number n

while (people <= 100)

{

System.out.println("Number of people: " + people);

// creating new birth day array

int[] newbirth_Day = new int[people];

int count = 0;

iteration = 100000;

while(iteration != 0)

{

count = 0;

for (int i = 0; i < newbirth_Day.length; i++)

{

// generating random birth day

int day = randNum.nextInt(365);

newbirth_Day[i] = birth_Day[day];

}

// check for same birthdays

for (int i = 0; i < newbirth_Day.length; i++)

{

int bday = newbirth_Day[i];

for (int j = i+1; j < newbirth_Day.length; j++)

{

if (bday == newbirth_Day[j])

{

count++;

break;

}

iteration = iteration - 1;

}

System.out.println("Probability: " + count + "/" + 100000);

System.out.println();

people += 5;

The directory "a" contains its subdirectory "b" and there is no other entry in the directory "a". You want to display "the conte

Svet_ta [14]

The answer assumes that the question is about which command help accomplish display directory contents in Unix-like operating systems.

Answer:

The command is ls.

Explanation:

The command ls (short for list) displays a variety of important information in different ways regarding any directory contents. Because of this, it is probably one of the most used commands in Unix-like operating systems.

Any directory can contain directories and files of different sizes, recently created/modified, attributes like permissions for being accessed, and, with this command, we can see all this information by size, chronologically, by owner, and/or by many more ways.

In the question, we can accomplish to list that the directory "a" contains its sub-directory "b" and no other entry using the next line of code:

Command-line 1: $\\ ls\; a$ (the command "says": display content of a)

Result: $b$

The result is only the directory b because there is no other entry in it.

To display more information regarding b, we can use the many options available for the command ls, like -a (all entries), -d (only directories), -l (long listing format), and so on, e.g. ls -a A (display all entries in directory A, included hidden files).

Which of the following answers refers to a system containing mappings of domain names to various types of data, such as for exam

Dvinal [7]

Answer:

Option B: DNS

Explanation:

Domain Name Server (DNS) is analogous to a phone book where people can look up a person name through numerical phone number. A DNS server is a database that host a database of public IP addresses (e.g. 64.233.160.0) and their associated hostname (e.g. google.com).

Whenever we type domain name in the address bar of our browser (e.g. google.com), that domain will be delivered to DNS server. Inside DNS server the URL will be mapped with its corresponding IP address making it possible for the web request to reach the the target server.
