Answer:
An observation: Java does not support true multi-dimensional arrays; rather, it supports 1-dimensional arrays, where each element can itself be another 1-dimensional array. The difference is the way memory is allocated, where a[i][j] differs from a[i,j].

Answer:
i) It is difficult to put the mouse pointer's insertion point in the text
ii) A gray border appear around the time and date when you point to it
Explanation:
When the date and time is pointed to or hovered using the mouse pointer, we have, that the background of the text changes to a grey border around the text when the date and time is inserted as a special object using the insert date and time button on the insert menu in the word processing application
The mouse pointer behaves different when working with some applications, and it could be difficult to place the insertion point of the mouse pointer in the text
Therefore, the correct options are;
<em>It is difficult to put the mouse pointer's insertion point in the text and</em>
<em>A gray border appear around the time and date when you point to it.</em>
Answer:
import java.util.*;
public class Main {
public static void main(String[] args)
{
Scanner scan = new Scanner();
double budget=0, num=0, total=0;
System.out.println("Your budget for the month? ");
budget=scan.nextDouble();
System.out.println("enter all expense, and after that type -9999 to quit: ");
while(num != -9999)
{
total+=num;
num=scan.nextDouble();
}
if(total<=budget)
{
System.out.println("under budget by ");
System.out.println(budget-total);
}
else
{
System.out.println("over budget by ");
System.out.println(total-budget);
}
}
}
Explanation:
- Take the budget as an input from user and store it to the budget variable.
- Loop until user has entered all his expenses and keep on adding them to the total variable.
- Check If the total is less than or equal to budget or otherwise, and then print the relevant message accordingly.
Answer:
Option d is the correct answer for the above question.
Explanation:
- The first loop of the program has a second loop and then the statement. In this scenario, the second loop executes for the value of the first loop and the statement executes for the value of the second loop.
- The first loop executes 4 times, Then the second loop or inner loop executes n times for the n iteration of the first loop, for example, 1 time for the first iteration of the first loop, 2 times for the second iteration of the first loop and so on.
- Then the inner loop executes (1+2+3+4) iteration which gives the result 10 iterations.
- The sum initial value is 0 and the "sum++", increase the value of the sum by 1.
- So the value of the sum becomes 10 after completing 10 iterations of the inner for loop.
- Hence the 10 will be the output. So the Option d is the correct answer while the other is not.
Answer:
The answer is A. CAD which means Computer-Aided Design.
Explanation:
CAD is used for creating different designs, simulations and scientific diagrams, some examples of CAD software include AutoCAD and Solidworks.
For reference the other acronyms mean:
Desktop publishing (DTP)
Computer-based training (CBT)
Web-based training (WBT)
