Which of the following Web sites would be MOST credible?

1 answer:

6 0

As of this problem together with the options presented with it, the most probable and the most likely answer for this would be A. a site associated with a local university.

An encyclopaedia site with many contributors can be prone to false information and made-up information. To add to it, some contributors might just be displaying the art of trolling over the internet and some might just be contributing just for the heck of it. A site run by a small, obscure publishing house can become more credible by becoming more renowned. A private site can either be good or bad, depending on the author that set it up. The most credible among the options would be a site associated with a local university.

return 0;

}

Explanation:

Read a number from usr and assign it to variable "num". If the input number is less than 1 or greater than 10 then ask again to enter a number until user enter a number between 1-10 only.Then with the help of switch() function print the equivalent Roman number.

Output:

Enter a number between 1 and 10: -5

Wrong input!!Enter again:12

Wrong input!!Enter again:6

The Roman numeral for 6 is:VI

Write a SQL query to find the population of the planet named 'Caprica' -- 10 points Find the first name, last name, and age of p

Artemon [7]

The question is incomplete! Complete question along with answer and step by step explanation is provided below.

Please find the attached question.

Answer:

a) SQL Query:

SELECT population

FROM bsg_planets

WHERE name='Caprica';

b) SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE lname!='Adama';

c) SQL Query:

SELECT name, population

FROM bsg_planets

WHERE population > 2600000000

d) SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE age IS NULL;

Explanation:

a) Write a SQL query to find the population of the planet named 'Caprica'

Syntax:

SELECT Column

FROM TableName

WHERE Condition;

For the given case,

Column = population

TableName = bsg_planets

Condition = name='Caprica'

SQL Query:

SELECT population

FROM bsg_planets

WHERE name='Caprica';

Therefore, the above SQL query finds the population of the planet named 'Caprica' from the table bsg_planets.

b) Find the first name, last name, and age of people from bsg_people whose last name is not 'Adama'

Syntax:

SELECT Column1, Column2, Column3

FROM TableName

WHERE Condition;

For the given case,

Column1 = fname

Column2 = lname

Column3 = age

TableName = bsg_people

Condition = lname!='Adama'

SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE lname!='Adama';

Therefore, the above SQL query finds the first name, last name and age of people whose last name is not 'Adama' from the table bsg_people.

c) Find the name and population of the planets with a population larger than 2,600,000,000

Syntax:

SELECT Column1, Column2

FROM TableName

WHERE Condition;

For the given case,

Column1 = name

Column2 = population

TableName = bsg_planets

Condition = population > 2600000000

SQL Query:

SELECT name, population

FROM bsg_planets

WHERE population > 2600000000

Therefore, the above SQL query finds the name and population of the planets with a population larger than 2,600,000,000 from the table bsg_planets.

d) Find the first name, last name, and age of people from bsg_people whose age is NULL

Syntax:

SELECT Column1, Column2, Column3

FROM TableName

WHERE Condition;

For the given case,

Column1 = fname

Column2 = lname

Column3 = age

TableName = bsg_people

Condition = age IS NULL

SQL Query:

SELECT fname, lname, age

FROM bsg_people

WHERE age IS NULL;

Therefore, the above SQL query finds the first name, last name and age of people whose age is NULL from the table bsg_people.

hodyreva [135]

Answer:

Programming Language not stated;

But this application definitely requires a graphical user interface platform (so, I'll use Microsoft Visual C# - Winforms).

Controls to be used are.

1. Form

2. List box

I'll name the Form, Form1 and the list box, listbox1.

Explanation:

The code goes thus;

private void Form1_Load(object sender, System.EventArgs e)

{

//Load country into empty listbox

listbox1.Items.Add("Austria");

listbox1.Items.Add("Canada");

listbox1.Items.Add("England");

listbox1.Items.Add("France");

listbox1.Items.Add("Italy");

listbox1.Items.Add("Mexico");

listbox1.Items.Add("Spain");

}

private void listbox1_SelectedIndexChanged(object sender, System.EventArgs e)

{

//Check if an item is really selected

if(listbox1.SelectedIndex >= 0)

{

//Index 0 represents 1st item that was added to the listbox and that's Austria

if(listbox1.SelectedIndex ==0)

{

MessageBox.Show("Vienna");

}

else if(listbox1.SelectedIndex == 1)

{

MessageBox.Show("Toronto");

}

else if(listbox1.SelectedIndex ==2)

{

MessageBox.Show("London");

}

else if(listbox1.SelectedIndex == 3)

{

MessageBox.Show("Paris");

}

else if(listbox1.SelectedIndex ==4)

{

MessageBox.Show("Rome");

}

else if(listbox1.SelectedIndex == 5)

{

MessageBox.Show("Mexico City");

}

else if(listbox1.SelectedIndex == 6)

{

MessageBox.Show("Madrid");

}

else

{

MessageBox.Show("No item selected");

}

Software as a service (SaaS)

Explanation:

Software as a service (SaaS) is a software licensing and release model in which the subscription basis of software licensing is done on a subscription basis and is centrally hosted. It is occasionally referred to as "on-demand software", and was in earlier times referred to as "software plus services" by Microsoft.

For instance, a company can write or build its own software packages and use the SaaS provider's APIs to incorporate those tools with the SaaS offering.
