Answer:

B: new ArrayList()

Explanation:

When dealing with Java syntax you always need to initialize an ArrayList object with its constructor. From the options listed the only correct option would be B: new ArrayList(). This would correctly initialize the ArrayList object but is not necessarily the recommended way of doing this. The truly recommended way would be the following

ArrayList<Thing> a = new ArrayList<Thing>()

Helga [31]

Answer:

Option(d) is the correct answer to the given question .

Explanation:

There are various type of algorithm is used for the purpose of the key scheduling such as AES .in the AES algorithm we used same key for encryption and decryption of text .The  main objective of the AES algorithm it is used by Various round of the similar plain text encryption to reinforce the cipher text.

  • The Option (a) is wrong because In the key scheduling the creating keys are not being used one after just another in the various communication cycles.
  • The Option (b) is wrong because In the key scheduling  we do not used the  the random key for the encryption process .
  • The Option (c) is wrong because we will never arbitrarily subdivided into groups of public and private key.

Taking a suitable example in c language explain the of call by value and call by reference concepts.
Degger [83]

Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.

Explanation:

Some examples are:

call by value

#include <stdio.h>  

void swap(int, int);

int main()

{  int a = 10, b= 20;

 swap(a, b);

 printf("a: %d, b: %d\n", a, b);

}  

void swap(int c, int d)

{

 int t;

 t = c; c = d; d = t;

}  

OUTPUT

a: 10, b: 20

The value of a and b remain unchanged as the values are local

//call by reference

#include <stdio.h>

 void swap(int*, int*);

 int main()

{

 int a = 10, b = 20;

 swap(&a, &b);   //passing the address

 printf("a: %d, b: %d\n", a, b);

}

void swap(int *c, int *d)

{

 int t;

 t = *c; *c = *d; *d = t;

}

OUTPUT

a: 20, b: 10

due to dereferencing by the pointer the value  can be changed which is call by reference
