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.
<span>If using excel, you can use this formula:
DATEDIF(start_date, end_date, unit)
For instance,
DATEDIF(9/1/2014, today, "d")
or
DATEDIF(B10, today, "d")</span>
Answer:
The correct answer is option (A).
Explanation:
Pinterest has turned to amazon for storage as a service because it continuously needs a large amount of storage as given in the scenario.
While the other options are not correct because of the following reasons:
- Grid computing can be defined as the concept of connection between a large number of computers in an architectural way who work to obtain the same goal but grid computing can not fulfill the need for storage for Pinterest.
- Cloud computing can work as data storage which can be accessed from the internet anywhere but this can not fulfill the storage requirements for Pinterest as they are very huge.
- Infrastructure as a service is not correct because the need of the company is for storage.
