What are the benefits of writing functions that use parameters and return List 2 please and explain what is return

Ratling [72]

<u>Answer and explanation:</u>

There are many benefits of writing functions that use parameters and return. Some of them are:

1. Flexibility: With functions having parameters, several values of the parameters can be used at invocation time thereby making the application flexible. For example, given the following function in Java.

<em>public void showName(String name){</em>

<em> System.out.println("Your name is " + name);</em>

<em>}</em>

To call this method (function), the programmer could use various values for the name parameter used in the function like so:

showName("John");

showName("Doe");

If the function didn't have a parameter, it is possible it will only print a hardcoded name every time the function is called.

2. Scope Control: When a function is allowed to return a value, it helps to work around scope issues since variables declared within a function are limited to that function and do not exist outside the function. This means that the values of these variables cannot be used anywhere else outside the function in which they are being declared. However, if the function returns a value, the value can be used anywhere else in the program.

For example:

<em>public String getDouble(int x){</em>

<em> int y = x * 2</em>

<em> return y;</em>

<em>}</em>

The function above returns twice the value of the argument supplied to it. Since the integer variable y is declared within the function, it's value cannot be used outside the function. However, since the value is being returned by the function, it could be used anywhere the function is being called. Thanks to the return keyword.

Recall that the name of a transport-layer packet is segment and that the name of a link-layer packet is frame. What is the name

AlladinOne [14]

Answer:

A network-layer packet is a data gram. A router forwards a packet based on the packet's IP (layer 3) address. A link-layer switch forwards a packet based on the packet's MAC (layer 2) address.

Explanation:

When the end system receives the unstructured bit stream from the physical wire, each layer removes the header information applicable to it until the application receives the data.

1. An application, such as an email program, creates data that will be sent by an end user, such as an email message. The Application layer places a header (encapsulation) field that contains information such as screen size and fonts, and passes the data to the Presentation layer.

2. The Presentation layer places layer 6 header information. For example, the text in the message might be converted to ASCII. The Presentation layer will then pass the new data to the Session layer (layer 5).

3. The Session layer follows the same process by adding layer 5 header information, such as information that the Session layer will manage the data flow, and passes this data to the Transport layer (layer 4).

4. The Transport layer places layer 4 information, such as an acknowledgement that the segment was received in the header, and passes it to the Network layer (layer 3).

5. The Network layer places layer 3 header information, such as the source and destination address so the Network layer can determine the best delivery path for the packets, and passes this data to the Data Link layer (layer 2).

6. The Data Link layer places layer 2 header and trailer information, such as a Frame Check Sequence (FCS) to ensure that the information is not corrupt, and passes this new data to the Physical layer (layer 1) for transmission across the media.

7. The bit stream is then transmitted as ones and zeros on the Physical layer. It is at this point that the Physical layer ensures bit synchronisation. Bit synchronisation will ensure the end user data is assembled in the correct order it was sent.

8. Steps 1 through 7 occur in reverse order on the destination device. Device B collects the raw bits from the physical wire and passes them up the

Data Link layer. The Data Link layer removes the headers and trailers and passes the remaining information to the Network layer and so forth until data is received by the Application layer. Eventually, Device B will receive an email notification displaying a message to indicate that a new email message has been received.

Create a structure representing a student. The member variables should include student name, student ID, and four test grades fo

Neporo4naja [7]

Answer:

Output:

Name: Brainly

ID:0001

Write the 4 tests grades of the student separated by space :10 9 8 10

Brainly

0001

10 9 8 10

Average :9.66667

'1' to continue '0' to exit :

Explanation:

#include<iostream>

#include<string>

using namespace std;

//variables declaration

struct Student {

string id; //string declaration ID

string name; // string declaration name

int grades[4]; //array of 4 because it is 4 grades

};

//definition of the function get information

void inputData(Student &s){

cout << "Name:" ;

getline(cin,s.name);

cout << "ID:";

cin >> s.id;

cout << "Write the 4 tests grades of the student separated by space :";

for (int i = 0; i<4; i++)

cin >> s.grades[i];

}

//definition of the function of average

double inputAvg(Student s){

double summation;

int temporary;

double average;

for (int i = 0; i<4; i++){

for (int j = i; j<4; j++){

if (s.grades[j] > s.grades[i]){

temporary = s.grades[i];

s.grades[i] = s.grades[j];

s.grades[j] = temporary;

}

}

}

summation = 0;

for (int i = 0; i<3; i++){

summation = summation + s.grades[i];

}

average = summation/3;

return average;

}

void disp(Student *s){

cout << s->name << endl;

cout << s->id << endl;

for (int i = 0; i<4; i++)

cout << s->grades[i] << " ";

cout << endl;

cout << "Average :" << inputAvg(*s) << endl;

}

int main(){

Student st;

int ch;

while(true){

inputData(st);

disp(&st);

cout << " '1' to continue '0' to exit :";

cin >> ch;

if (ch == 0)

break;

}

return 0;
