Not sure what quizScore1-5 is, but here it is. Also, I'm not entirely sure what language you're working with here, but null can't be returned as an integer. If it were a string, for example, it'd be possible as string is an object reference type.

public int getData(int dataNumber)
{
if (dataNumber == 1)
return quizScore1;
else if (dataNumber == 2)
return quizScore2;
else if (dataNumber == 3)
return quizScore3;
else if (dataNumber == 4)
return quizScore4;
else if (dataNumber == 5)
return quizScore5;
else
return 0;
}

The definition of network is:

kondaur [170]

$\text{Hello there!}$

Networks were originally used as a government weapon 61 years ago to communicate information such as data and research. However, individual networks were eventually discontinued by the government and made open to the public to use for things such as PAN, LAN, MAN, WAN, SAN, and so on.

Our internet today is capable of communicating with bilions of computers. This is possible due to your modem using radio wave-like speeds to connect to your ISP. Your ISP then connects to a larger network, which is connecting to thousands of other networks. You see, the internet is just a large network of networks that are connected through very fast radiowaves. However, it is not just a single network being used anymore; it's thousands of them. The term, "internet" was used to describe this large selection of networks. In short, B would be incorrect.

The worldwide web is a protocol used by the internet to connect to select websites favourably from whoever's using it. This obviously would not define the network, as this is something that's used by it. Furthermore, A would not be correct.

As described already, the network was a selection of computers used to communicate information to each other. C would not be correct as it states that there is only one computer being used.

$\fbox{Therefore, D would be the correct answer.}$

What will be displayed after code corresponding to the following pseudocode is run? Main Set OldPrice = 100 Set SalePrice = 70 C

Tatiana [17]

Answer:

A jacket that originally costs $ 100 is on sale today for $ 80

Explanation:

Main : From here the execution of the program begins

Set OldPrice = 100 -> This line assigns 100 to the OldPrice variable

Set SalePrice = 70 -> This line assigns 70to the SalePrice variable

Call BigSale(OldPrice, SalePrice) -> This line calls BigSale method by passing OldPrice and SalePrice to that method

Write "A jacket that originally costs $ ", OldPrice -> This line prints/displays the line: "A jacket that originally costs $ " with the resultant value in OldPrice variable that is 100

Write "is on sale today for $ ", SalePrice -> This line prints/displays the line: "is on sale today for $ " with the resultant value in SalePrice variable that is 80

End Program -> the main program ends

Subprogram BigSale(Cost, Sale As Ref) -> this is a definition of BigSale method which has two parameters i.e. Cost and Sale. Note that the Sale is declared as reference type

Set Sale = Cost * .80 -> This line multiplies the value of Cost with 0.80 and assigns the result to Sale variable

Set Cost = Cost + 20 -> This line adds 20 to the value of Cost and assigns the result to Cost variable

End Subprogram -> the method ends

This is the example of call by reference. So when the method BigSale is called in Main by reference by passing argument SalePrice to it, then this call copies the reference of SalePrice argument into formal parameter Sale. Inside BigSale method the reference &Sale is used to access actual argument i.e. SalePrice which is used in BigSale(OldPrice, SalePrice) call. So any changes made to value of Sale will affect the value of SalePrice

So when the method BigSale is called two arguments are passed to it OldPrice argument and SalePrice is passed by reference.

The value of OldPrice is 100 and SalePrice is 70

Now when method BigSale is called, the reference &Sale is used to access actual argument SalePrice = 70

In the body of this method there are two statements:

Sale = Cost * .80;

Cost = Cost + 20;

So when these statement execute:

Sale = 100 * 0.80 = 80

Cost = 100 + 20 = 120

Any changes made to value of Sale will affect the value of SalePrice as it is passed by reference. So when the Write "A jacket that originally costs $ " + OldPrice Write "is on sale today for $ " + SalePrice statement executes, the value of OldPrice remains 100 same as it does not affect this passed argument, but SalePrice was passed by reference so the changes made to &Sale by statement in method BigSale i.e. Sale = Cost * .80; has changed the value of SalePrice from 70 to 80 because Sale = 100 * 0.80 = 80. So the output produced is:

A jacket that originally costs $ 100 is on sale today for $ 80
