d. SELECT

"SELECT" is a part of a DML statement.

What is DML?

DML, or Data Manipulation Language, is a subset of database operations used to insert, delete, and update data. A DML is frequently a sublanguage of a larger language, such as SQL; DML includes some of the language's operators. Because some users can perform both read and write selection, selecting read-only data is closely related to and sometimes considered a component of a DML.

Structured Query Language, or SQL, is a popular data manipulation language that is used to retrieve and manipulate data in a relational database. SQL allows you to perform database operations as well as create databases. SQL performs the required tasks by using specific commands such as Create, Drop, Insert, and so on.

Explain the steps you take to complete an Internet search. Do you use a particular search engine every time or do you alternate?

Naddik [55]

1. Personally, I always use the same search engine, which is Google. I once opened Bing mistakenly, but obviously returned to Google immediately. Google is my preferred choice because I've used it for such a long time that I've gotten so used to it and cannot change it. The other search engines don't look as appealing to me as Google.

2. Some advantages would be definitely the format of the information you get from a search engine as opposed to the metasearch engine - sometimes, the metasearch engine cannot provide you with complete results or even complete sentences, so you may be left with illegible texts. On the other hand, metasearch engines can give you so much more information than regular search engines.

3. If the credentials seem legit, based on particular rules as to how to write sources used (such as Chicago style, APA, etc.), then you can safely assume the source is credible. If the author wrote everything necessary in his text (especially works cited/links available), you can usually trust that source.

1. What is the main factor that affects Earth’s average temperature?

user100 [1]

Answer:

1. The Sun is the primary source of energy that influences any planet's temperature, including Earth. The amount of energy received from the Sun is called insolation; the ratio reflected is called the albedo.

2.There are three major ways in which global warming will make changes to regional climate: melting or forming ice, changing the hydrological cycle (of evaporation and precipitation) and changing currents in the oceans and air flows in the atmosphere

3.The warming of Earth is primarily due to accumulation of heat-trapping greenhouse gases, and more than 90 percent of this trapped heat is absorbed by the oceans. As this heat is absorbed, ocean temperatures rise and water expands. This thermal expansion contributes to an increase in global sea level.

4.The main sources of greenhouse gases due to human activity are: burning fossil fuels leading to higher carbon dioxide concentrations. farming and forestry — including land use change via agriculture and livestock. cement manufacture.

5. - Reduce, Reuse, Recycle

- Use Less Heat and Air Conditioning

-Use Less Hot Water

Convert infix to postfix

kvv77 [185]

Answer:

static int checkSymbol(char ch)

{

switch (ch)

{

case '+':

case '-':

return 1;

case '*':

case '/':

return 2;

case '^':

return 3;

}

return -1;

}

static String convertInfixToPostfix(String expression)

{

String calculation = new String("");

Stack<Character> operands = new Stack<>();

Stack<Character> operators = new Stack<>();

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

{

char c = expression.charAt(i);

if (Character.isLetterOrDigit(c))

operands.push(c);

else if (c == '(')

operators.push(c);

else if (c == ')')

{

while (!operators.isEmpty() && operators.peek() != '(')

operands.push(operators.pop());

if (!operators.isEmpty() && operators.peek() != '(')

return NULL;

else

operators.pop();

}

else

{

while (!operators.isEmpty() && checkSymbol(c) <= checkSymbol(operators.peek()))

operands.push(operators.pop());

operators.push(c);

}

while (!operators.isEmpty())

operands.push(operators.pop());

while (!operands.isEmpty())

calculation+=operands.pop();

calculation=calculation.reverse();

return calculation;

}

Explanation:

Create the checkSymbol function to see what symbol is being passed to the stack.
Create the convertInfixToPostfix function that keeps track of the operands and the operators stack.
Use conditional statements to check whether the character being passed is a letter, digit, symbol or a bracket.
While the operators is not empty, keep pushing the character to the operators stack.
At last reverse and return the calculation which has all the results.

Design a class named Cake. Data fields include two string fields for cake flavor and icing flavor and numeric fields for diamete

kkurt [141]

Using the computer language in pseudocode to write a function code that declares two Cake objects and sets and displays their values.

<h3>Writting the code in pseudocode:</h3>

- cake flavor: string

- icing flavor: string

-diameter: num

-price: num

+set cake flavor (cake flavor : string) : void

+set icing flavor (icing flavor: string) : void

+set Diameter(size : num) : void

+set Price(price : num) : void

+get cake flavor () : string

+get cing flavor () : string

+get Diameter() : num

+get Price() : num

Answer A=

Pseudocode:

class Cake

Declarations

private string cake flavour

private string icing flavor

private num diameter

private num price

public void set Cake flavour (string Cake flavour)this. Cake flavour = Cake flavour

return

public void set icing flavour (string icing flavour)this. icing flavour = icing flavour

return

public void set Diameter(num size)

diameter = size

return

public void set Price(num price)

this price = price

return

public string get Cake flavour ()

return Cake flavour

public string get icing flavour ()

return icing flavour

public num get Diameter()

return diameter

public num get Price()

return price

end Class

start

Declarations

Cake my Cake

Cake your Cake

myCake.set cake flavour (“chocalate”)

myCake.set icing flavour (“peppermint”)

myCake.setDiameter(15)

myCake.setPrice(18)

myCake.set cake flavour (“pineapple”)

myCake.set icing flavour (“orange ”)

yourCake.setDiameter(20)

yourCake.setPrice(25)

output “Cake 1 info:”

output myCake.get cake flavour ()

output myCake.get icing flavour ()

output myCake.getDiameter()
