Answer:

A traditional database has a static memory space, and at times this can be more than what you need, and this happens almost always. However, in the case of a cloud database, you are allowed to choose the DB space that you feel will be used, and you can scale it up and down anytime according to the demand. Suppose more user is using your software, you can scale up the database, or else you can scale down. And you are going to pay for what DB space you used, and for how long. And that is why the cloud database cost is less than a traditional database.

Tpy6a [65]

Answer:

Code in C++

Explanation:

C++ Code

#include<iostream> //for input and output  

using namespace std;  

int main()  

{  

  int hour;

  int minute;

  cout<<"Enter the hour:";

  cin>> hour;

  cout<<"Enter the minute:";

  cin>>minute;

  minute = minute+15;

  if(minute>=60){

   hour++;

   minute=minute-60;

  }

  if(hour>=24){

   hour=0;

  }

  cout<<"Hours: "<<hour<<endl;

  cout<<"Minutes:"<<minute;

  return 0;  

}

Code Explanation

First we need to declare two int variables to hold hour and minute values input from user.

Check if by adding 15 minutes into minute entered by user is greater then or equal to 60 then increment into hour and subtract 60 from minute.

Another check is that if user enters more then 24 hour or by making increment into hour, the hour values i greater then or equal to 24 then we need to change the hour to 0.

Result

Case 1:

Enter the hour:8

Enter the minute:15

Hours: 8

Minutes:30

Case 2:

Enter the hour:9

Enter the minute:46

Hours: 10

Minutes:1

50 60

Explanation:

Given

The above code segment

Required

What is printed, if anything

To do this, we analyze the code line by line.

Line 1: The first line creates a 4 by 3 array named mat

Line 2: for (int[] row : mat) {  -> This creates row[] array which represents each row of array mat

Line 3: for (int j = 0; j < row.length; j += 2){ -> This iterates through the even indexed elements of the row array i.e. 0 and 2

Line 4: System.out.print(row[i] + " "); -> This prints the even indexed elements of the row array.

The even indexed elements are: 10, 20, 30, 40, 50 and 60

Line 5: System.out.println(); --> This prints a new line

What is the most important factors to consider when designing a powerpoint presentation?
balandron [24]
It is always helpful to choose a template, and an attractive theme to begin with. Next, display only the keywords or phrases that you need in your PowerPoint. This will help it look less boring (if its a whole paragraph of writing, it looks boring). Lastly, it is important to add visuals or images to your PowerPoint. Google Slides is also very convenient to use. Please message me if you have any other concerns!
