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
Answer:
10 20
30 40
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
Having to compare results on experiments or lab tests to each other.

just took the exam ... hope it helps
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!
