Answer:
Java code is given below
Explanation:
import java.util.Scanner;
public class Prime {
public static void main(String args[]) {
int first, last, flag = 0, i, j;
Scanner s = new Scanner(System.in);
System.out.println("Enter the lower limit :");
first = s.nextInt();
System.out.println("Enter the upper limit :");
last = s.nextInt();
System.out.println("The prime numbers in between the entered limits are :");
int x = 0;
for (i = first; i <= last; i++) {
for (j = 2; j < i; j++) {
if (i % j == 0) {
flag = 0;
break;
} else {
flag = 1;
}
}
if (flag == 1) {
x++;
System.out.println(i + " ");
}
}
System.out.println("Total number of prime numbes between " + first + " and " + last + " are " + x);
}
}
Answer:
d. A subclass reference can be assigned to a superclass variable, but a superclass reference cannot be assigned to a subclass variable.
Explanation:
A subclass is a class which is derived from another class. A subclass will have the characteristics of its ancestor class. A superclass is a class which is class direct ancestor. A superclass is an existing class from which new classes are derived whereas subclass is a class which is derived from superclass. The correct statement is that a subclass can be assigned to a superclass variable.
Answer:
In the CIA Triad, "Confidentiality" means ensuring that data is
Explanation:
protected from unauthorized changes to ensure that it is reliable and correct.
Answer:
There is only one modification in the above loop i.e. while loop should be like this--
while (i != n)
{
sum+=arr[i]; // Line 1, In question segment it is line 2.
i++; // Line 2, In question segment it is line 1.
}
Output:
Now if the array input is 1,2,3,4,5 then the output is 15.
Explanation:
In the above question, all the line of the segment is right except the body of the loop because--
- The First line of the loop is increment statement which increments the value of "i" variable from 1 and the value of "i" variable will be 1 in the first iteration of the loop
- The second line starts to add the value from 1'st index position of the array. Hence the segment gives the wrong answer. It adds the arr[1] to arr[n-1].
- So I interchanged both lines of the while loop as shown in the answer part. I make the line 1 (In question segment) as line 2(In answer part) and line 2 (In question segment) as line 1 (In answer part).
Now It gives the correct output because it can add arr[0] to arr[n-1].
