Answer:
The concealment cipher.
Explanation:
A concealment cipher also known as null cipher can be defined as an obsolete encryption format that typically involves the mixture of plaintext with non-cipher elements. This ultimately implies that, the plaintext is hidden in another message through encryption.
The concealment cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem.
Basically, the concealment cipher is solely dependent on the clues of the physical factors that mainly affects the sender and receiver in a communication system.
Answer:
Option (d) is correct.
Explanation:
In java language "ar.length" is used to tells the size of the array. The array is used to declare more than one variable. Its index value is started from 0. so when a user needs to initialize the value of an array, they need to start the index value at 0. because ar[0] indicates the first variable of an array.
In option (d), index value is started from 0 and ends with (array_size-1). so it gives the accessed to all the variable of an array and the statement "ar[i]=4;", initialize the value 4 to all array variable.
while another option is not valid because--
- In option a, Index value starts from 1 which accesses the second variable of an array.
- In option b, the statement "i<= ar.length;", gives an unbound array exception because it took the size greater than the array size.
- In option c, statement "i<ar.length-1;", can not give accessed to the last element of an array.
