Answer:
The answer to this question can be given as:
Class definition:
public class Averager //define class Average.
{
private int sum = 0;
//define variable sum.
private int count = 0;
//define variable count.
public int getSum() //define function getSum().
{
return sum; //return value.
}
public void add(int x)
//define function add().
{
sum = sum + x; //calculate sum
count=count+1; //increase value of count.
}
public int add(int x)
//define function add().
{
return count; //return value.
}
public double getAverage() //define function getAverage().
{
return (double)sum/count; //return value
}
}
Explanation:
The above class definition can be described as:
- In the above class definition first we define a class that is " Averager". In this class we define two integer variable that is "sum and count" and assign a value that is 0. Then we define a functions :
- First we define getSum() function in this function we does not pass any value and the return type of this function is int that will return an integer value.
- Then we define add() function we use this function two times but both functions have different from each other.
- In first time implementation, we define this function and the return type of this function is void which means it does not return any value. In this function, we calculate the sum value and increase the value of the count variable by 1.
- In second time implementation, we define this function and the return type of this function is int which means it will return a value. In this function, we will return the count variable value.
- At the last, we define a getAverage() that calculates the average of the added values in the sum variable and returns its value.
Answer:
SMTP
Explanation:
This is the SMTP or the Simple Mail Transfer Protocol. It is the push protocol and is used to send the mail message. Whereas POP3 and IMAP are meant for retrieving the message. These are the three main types of protocols associated with mail services. And the correct answer here is certainly the SMTP.
Answer:
Answered below.
Explanation:
#Answer is written in Python programming language
#Get inputs
radius = float(input("Enter radius in inches: "))
height = float(input("Enter height in feet: "))
#Convert height in feet to height in inches
height_in_inches = height * 12
#calculate volume in cubic inches
volume = 3.14 * (radius**2) * height_to_inches
#convert volume in cubic inches to volume in gallons
volume_in_gallons = volume * 0.00433
#output result
print (volume_in_gallons)
Answer:
File manager
Explanation:
From the list of options 1 to 4, only option (2) is correct
Explaining the options one after the other
- Web browser: It lets users access the internet
- File Manager: Used to create and manage files/folders
- User Interface: Means which the user of a computer interacts with the computer
- File Reader: Used to read the content of a file. e.g. Adobe reader for pdf files, Notepad for text files, etc.
Having explained the options one after the other, <em>the file manager </em>is the answer to this question.
